| CVE-2026-98377 | 1 Linux | 1 Linux Kernel | 2026-10-11 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: vlan: require the MAC header to be present in __vlan_insert_inner_tag() __vlan_insert_inner_tag() only guarantees head room via skb_cow_head(), never that mac_len bytes of MAC header are present. Its ETH_HLEN wrappers - __vlan_insert_tag() under skb_vlan_push(), and vlan_insert_tag() under validate_xmit_vlan() on the generic transmit path - therefore rewrite the first 16 bytes at skb->data: a 12-byte memmove plus two 2-byte stores at +12 and +14. No caller supplies the bound, while the pop helpers use skb_ensure_writable()/pskb_may_pull(). An IFF_TUN device has hard_header_len == 0, so packet_snd() accepts a one-byte AF_PACKET/SOCK_RAW frame. The first vlan push only sets a hwaccel tag; the next - clsact "action vlan push" or bpf_skb_vlan_push() - enters the helper with skb->len still 1. The head comes from skbuff_small_head without __GFP_ZERO, so each push drags bytes from beyond skb->tail into the frame. After three the one-byte send leaves as 13 bytes carrying 11 bytes of uninitialised slab: 0000: 5a b3 62 12 80 88 ff ff 00 b3 62 12 81 `------------------------------' only 0x5a was sent; the rest is slab, here the top 56 bits of a linear-map address Require the MAC header the helper rewrites to be present, so such a frame is dropped rather than transmitted. | ||||
| CVE-2026-98348 | 1 Linux | 1 Linux Kernel | 2026-10-11 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: libipw: reject too-short association responses libipw_handle_assoc_resp() reads the capability, status and aid fields of the 30-byte association response prefix and then computes the information element length as stats->len - sizeof(*frame) stats->len is a u16 and sizeof() has type size_t, so the subtraction is evaluated as size_t and wraps instead of going negative. Truncating that to the u16 length parameter of libipw_parse_info_param() turns a frame shorter than the fixed fields into a length near 64 KiB, and the parser then reads past the receive buffer. Both the ipw2100 and ipw2200 management receive paths reach this function having established only that the frame carries the generic 24-byte three-address header. Reject the frame before any fixed field is touched. Found by an AI-assisted review of length arithmetic in management frame parsers. Verified with a KUnit case under Generic KASAN on arm64 under QEMU; I do not have the hardware, so it is not tested on a real device. | ||||
| CVE-2025-31200 | 1 Apple | 6 Ipados, Iphone Os, Macos and 3 more | 2026-10-10 | 9.8 Critical |
| A memory corruption issue was addressed with improved bounds checking. This issue is fixed in iOS 18.4.1 and iPadOS 18.4.1, macOS Sequoia 15.4.1, tvOS 18.4.1, visionOS 2.4.1, watchOS 11.5. Processing an audio stream in a maliciously crafted media file may result in code execution. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS released before iOS 18.4.1. | ||||
| CVE-2026-107634 | 1 Aorimn | 1 Dislocker | 2026-10-10 | 6.1 Medium |
| Dislocker through 0.7.3 contains a heap out-of-bounds read vulnerability in get_dataset() and get_next_datum() that never validate dataset and datum sizes against the metadata allocation. Attackers can craft a BitLocker volume image with inflated dataset or datum sizes that, when opened or mounted, crashes dislocker or discloses adjacent heap memory. | ||||
| CVE-2026-107161 | 2 Cyrusimap, Redhat | 6 Cyrus-sasl, Enterprise Linux, Hardened Images and 3 more | 2026-10-10 | 7.5 High |
| A heap-based buffer overflow flaw was found in Cyrus SASL. The add_to_challenge() function in the DIGEST-MD5 plugin computes the size of the buffer needed for a challenge/response field before DIGEST-MD5 quoting is applied, but does not recompute that size when quoting (escaping special characters) makes the value longer. The under-sized buffer is then passed to strcat(), causing a heap-based out-of-bounds write whose size depends on attacker-controlled input. A malicious or on-path DIGEST-MD5 (or HTTP Digest) server can trigger this flaw in a connecting client by supplying a crafted challenge field, such as realm or nonce, most likely resulting in a crash of the client application. | ||||
| CVE-2026-98221 | 1 Linux | 1 Linux Kernel | 2026-10-10 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: KEYS: trusted: Fix tpm2_load_cmd() boundary check tpm2_load_cmd() does boundary checks against the ASN.1 size i.e., payload->blob_len. Address this by passing the decoded blob size to tpm2_load_cmd(), and use it for the boundary checks. | ||||
| CVE-2026-98226 | 1 Linux | 1 Linux Kernel | 2026-10-10 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: mm, swap: fix SWAP_USAGE_OFFLIST_BIT collision with real usage count SWAP_USAGE_OFFLIST_BIT is embedded in the si->inuse_pages usage counter, and is meant to sit above any value that counter can reach. However, it is defined from BITS_PER_TYPE(atomic_t), so it is bit 30. On a system with 4 KiB pages the flag collides with the usage count once that count reaches 4 TiB. swap_usage_in_pages() masks bit 30 out, so whenever the real count has that bit set, every caller of it reads 4 TiB low: * /proc/swaps understates Used by 4 TiB. * A raw count of exactly 2^30 masks to zero, so try_to_unuse() takes its "if (!swap_usage_in_pages(si)) goto success;" early exit and swapoff tears the device down while pages are still swapped out. Nothing in the rest of swapoff aborts the teardown, so those pages are lost. Independently of swapoff, the collision also corrupts the counter and the plist. On a device in normal use, a free that leaves bit 30 set in the count makes swap_usage_sub() see the flag where there is only count, and call add_to_avail_list(). It clears the bit with fetch_and(~SWAP_USAGE_OFFLIST_BIT), leaving the stored count 4 TiB below the real one, and calls plist_add() on a device that is already listed, tripping the WARN_ON(!plist_node_empty(node)) in plist_add() and linking the node a second time. Change the definition of SWAP_USAGE_OFFLIST_BIT to be based on atomic_long_t instead. Note that the usage counter field itself is of this same type, so it is still a valid bit. | ||||
| CVE-2026-75346 | 1 Eipstackgroup | 1 Opener | 2026-10-10 | 7.5 High |
| An out-of-bounds read vulnerability exists in EIPStackGroup OpENer v2.3 and master through commit 76b95cf in the server-side CIP SetAttributeList service. This allows a remote attacker to cause a denial of service | ||||
| CVE-2026-75351 | 1 Eipstackgroup | 1 Opener | 2026-10-10 | 7.5 High |
| OpENer v2.3/commit 76b95cf, contains an out-of-bounds read in the server-side EtherNet/IP ForwardOpen connection-path parser. This allows a remote attacker to cause a denial of service. | ||||
| CVE-2026-75348 | 1 Eipstackgroup | 1 Opener | 2026-10-09 | 7.5 High |
| An out-of-bounds read vulnerability exists in EIPStackGroup OpENer v2.3 and master up to commit 76b95cf in the EtherNet/IP TCP SendRRData Common Packet Format parser. The issue occurs in CreateCommonPacketFormatStructure() when it parses recognized optional socket address information items of type 0x8000 or 0x8001 without first validating that the remaining CPF buffer contains the complete fixed sockaddr structure. This allows a remote attacker to cause a denial of service. | ||||
| CVE-2026-107845 | 1 Contao | 1 Contao | 2026-10-09 | 9.3 Critical |
| Contao is an Open Source CMS. From version 4.0.0 until 5.3.50 and 5.7.12, an unauthenticated visitor can submit a comment whose email or website metadata is rendered without sufficient attribute and URL encoding by listComments() in comments-bundle/contao/dca/tl_comments.php. When a backend user opens the Comments module, attacker-controlled script can execute in the Contao backend origin under that user's session. Unpublished comments remain visible to moderators, so moderation does not prevent exposure. This issue is fixed in versions 5.3.50 and 5.7.12. | ||||
| CVE-2012-2524 | 1 Microsoft | 1 Office | 2026-10-09 | N/A |
| Microsoft Office 2007 SP2 and SP3 and 2010 SP1 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted Computer Graphics Metafile (CGM) file, aka "CGM File Format Memory Corruption Vulnerability." | ||||
| CVE-2026-75353 | 1 Eipstackgroup | 1 Opener | 2026-10-09 | N/A |
| OpENer v2.3/ commit 76b95cf, contains an out-of-bounds read in the server-side EtherNet/IP ForwardOpen connection-path parser. This allows a remtoe attacker to cause a denial of service | ||||
| CVE-2026-73661 | 2 Freepbx, Sangoma | 2 Freepbx Framework, Freepbx | 2026-10-09 | 6.5 Medium |
| FreePBX is an open source IP PBX. Prior to 16.0.47 and 17.0.30, the FreePBX Framework module permits a crafted backup to restore the hidden AUTHTYPE setting with the value none through runRestore() in amp_conf/htdocs/admin/libraries/Builtin/Restore.php. An authenticated user with sufficient backup-restore access or write access to backup files can thereby disable FreePBX authentication during restoration, bypassing the user-interface removal of AUTHTYPE=none. This issue is fixed in versions 16.0.47 and 17.0.30. | ||||
| CVE-2026-107836 | 1 Riot-os | 1 Riot | 2026-10-09 | N/A |
| RIOT is an open-source microcontroller operating system designed for Internet of Things devices and other embedded systems. In 2026.07 and earlier, the nanoCoAP client function nanocoap_sock_get_slice() in sys/net/application_layer/nanocoap/sock.c accepts a Block2 response when _block_cb() sees the expected block number without also verifying that the server-controlled szx and derived offset match the requested block geometry. A malicious CoAP server can return the expected block number with a larger block size, causing the derived offset to exceed the client slice offset and making ctx->offset - offset underflow in _2buf_slice(). The resulting buffer-relative calculation can read before the payload buffer and crash the client, causing denial of service and potentially exposing adjacent memory. No fixed release is available as of this review. | ||||
| CVE-2015-2467 | 1 Microsoft | 1 Office | 2026-10-09 | N/A |
| Microsoft Office 2007 SP3 allows remote attackers to execute arbitrary code via a crafted document, aka "Microsoft Office Memory Corruption Vulnerability." | ||||
| CVE-2015-5477 | 13 Apple, Canonical, Debian and 10 more | 79 Os X Server, Ubuntu Linux, Debian Linux and 76 more | 2026-10-09 | 7.5 High |
| named in ISC BIND 9.x before 9.9.7-P2 and 9.10.x before 9.10.2-P3 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via TKEY queries. | ||||
| CVE-2026-106122 | 2 Rabbitmq, Vmware | 3 Amqp-client, Java-client, Rabbitmq Java Client | 2026-10-09 | 7.5 High |
| The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.36.0, ValueReader.readShortstr decodes malformed UTF-8 bytes into replacement characters that can re-encode beyond the AMQP shortstr limit enforced by ValueWriter.writeShortstr. An attacker who can submit an RPC message with a malformed echoed property can cause reply publication in RpcServer.mainloop() or tutorial-style consumers to throw an unchecked exception before acknowledgement. The broker requeues the message, allowing the same message to disable replacement consumers until the queue is purged. This issue is fixed in version 5.36.0. | ||||
| CVE-2026-19570 | 1 Zephyrproject | 1 Zephyr | 2026-10-09 | 8.8 High |
| The LE Audio Broadcast Sink in subsys/bluetooth/audio/bap_broadcast_sink.c copies subgroup metadata from a received Basic Audio Announcement (BASE) into the static Broadcast Audio Scan Service parameter structure mod_src_param without any bounds check. In base_subgroup_meta_cb() the destination element was selected as mod_src_param.subgroups[mod_src_param.num_subgroups] with no test against ARRAY_SIZE(mod_src_param.subgroups) (sized by CONFIG_BT_BAP_BASS_MAX_SUBGROUPS, default 1), and the metadata was copied with memcpy() using the raw on-air length returned by bt_bap_base_get_subgroup_codec_meta() into a metadata array sized by CONFIG_BT_AUDIO_CODEC_CFG_MAX_METADATA_SIZE (default 4). The BASE validator bt_bap_base_get_base_from_ad() only checks structural consistency and permits up to ~24 subgroups and metadata LTVs of ~240 octets. The defect is reached from the periodic advertising receive callback: pa_recv() → bt_data_parse() → pa_decode_base() → update_recv_state_base() → bt_bap_base_foreach_subgroup() → base_subgroup_meta_cb(). Every broadcast sink registers a scan-delegator receive state at creation (bt_bap_broadcast_sink_create() calls broadcast_sink_add_src()), and CONFIG_BT_BAP_BROADCAST_SINK depends on CONFIG_BT_BAP_SCAN_DELEGATOR, so the path is active in every broadcast-sink build once the device is periodic-advertising-synced. An attacker in radio range who operates a broadcast source the device syncs to — or who impersonates the advertiser address and SID of one already in use, periodic advertising data being unauthenticated — can change the BASE at will; each new BASE is re-parsed. A crafted BASE therefore writes attacker-chosen bytes past the end of a fixed static object in .bss: up to roughly 236 bytes for an oversized metadata LTV, plus whole struct bt_bap_bass_subgroup records for each subgroup beyond CONFIG_BT_BAP_BASS_MAX_SUBGROUPS. This is memory corruption of adjacent Bluetooth-audio state reachable with no pairing, bonding or GATT connection, with a potential for remote code execution in the Bluetooth RX thread; in addition, the unvalidated metadata_len is forwarded to bt_bap_scan_delegator_mod_src(), which neither clamps it nor rejects it, leading to a further copy into the receive state and to out-of-bounds memory being disclosed in the BASS receive-state notification sent to a connected Broadcast Assistant. The fix rejects a BASE carrying more subgroups than the receive state can hold (discarding the update entirely) and omits metadata that does not fit rather than copying it, and additionally honours the previously-ignored error return of the subgroup decode pass. | ||||
| CVE-2026-19569 | 1 Zephyrproject | 1 Zephyr | 2026-10-09 | 8.8 High |
| dynamic_object_create() in kernel/userspace/userspace.c computed the backing allocation for a dynamically allocated kernel object as obj_size_get(otype) + size, and for thread stack elements as STACK_ELEMENT_DATA_SIZE(size) (a round-up plus fixed overhead), without checking either expression for unsigned wrap-around. A size close to SIZE_MAX makes the computed total wrap to a very small value, so the heap chunk handed out is a few bytes while the object descriptor is still tagged with the full requested type and registered in the kernel object table. The size argument reaches that arithmetic directly from user mode. k_object_alloc_size() is declared __syscall in include/zephyr/sys/kobject.h, its verifier z_vrfy_k_object_alloc_size() in kernel/userspace/userspace_handler.c is a bare pass-through, and z_object_alloc() only range-checks otype — nothing bounds size. The stack-element branch is additionally reachable through the k_thread_stack_alloc() syscall via kernel/dynamic.c. Because subsequent kernel-object validation checks only the object's type and initialization state, the undersized handle passes K_SYSCALL_OBJ_INIT()/K_SYSCALL_OBJ_NEVER_INIT(), and the matching init syscall (for example k_mutex_init(), k_sem_init(), or k_thread_create()) then writes a complete object over the truncated allocation. An unprivileged user-mode thread can therefore trigger a supervisor-mode out-of-bounds write into the kernel resource-pool heap, of a size and content it substantially controls, corrupting sys_heap chunk metadata and adjacent kernel objects. Under CONFIG_GEN_PRIV_STACKS the thread-stack branch additionally stores an attacker-influenced wild pointer as a user thread's privileged stack base. The practical result is escape from the CONFIG_USERSPACE sandbox — kernel-level code execution or at minimum kernel memory corruption and system compromise. Exploitation requires CONFIG_USERSPACE together with CONFIG_DYNAMIC_OBJECTS (also selected by CONFIG_DYNAMIC_THREAD under userspace), and a calling thread with an assigned resource pool. The fix rejects both overflowing computations and frees the partially built descriptor. | ||||
