| Improper Validation of Specified Quantity in Input vulnerability in WP Desk Flexible Quantity – Measurement Price Calculator for WooCommerce flexible-quantity-measurement-price-calculator-for-woocommerce allows Input Data Manipulation.This issue affects Flexible Quantity – Measurement Price Calculator for WooCommerce: from n/a through 2.3.22. |
| A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory. |
| Heap-based buffer overflow vulnerability in Samsung Opensource rlottie allows Buffer Overflow via Environment Variables.
This issue affects rlottie: e57b094f03c39a751a1fded6f7d6c13f1ed95ec9. |
| lwIP SMTP client does not check the size of inputs, potentially allowing a buffer overflow. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel_pcie: validate TX skb length in send_sync
btintel_pcie_prepare_tx() copies skb->len bytes into a fixed
BTINTEL_PCIE_BUFFER_SIZE (4096) DMA slot via an unchecked memcpy.
Oversized packets are currently rejected only in
btintel_pcie_send_frame(); any future caller of
btintel_pcie_send_sync() would silently overflow the DMA buffer.
Add the bounds check in btintel_pcie_send_sync() itself, right
before skb_push() and the DMA copy. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix handling of NFSEXP_PNFS in the netlink codepath
The rework of how block layouts were checked moved the check for
NFSEXP_PNFS out of nfsd4_setup_layout_type() and into the callers. That
patch didn't account for the new call in nfsd4_setup_layout_type(). |
| Subscriber Bypass Vulnerability in MicroPayments <= 3.2.9 versions. |
| libexpat before commit 13c5f63 contains a heap buffer over-read vulnerability in xmlparse.c. XML_ParseBuffer advances the parse buffer end with parser->m_bufferEnd += len using a caller-supplied length that is not validated against the allocated buffer size, so repeated XML_ParseBuffer calls move m_bufferEnd past the end of the heap allocation and subsequent parsing reads out of bounds. Reaching this path requires a parse buffer to already be present; otherwise XML_ParseBuffer returns XML_ERROR_NO_BUFFER. A buffer is present after a prior call to XML_GetBuffer, either directly (the common case) or indirectly through a prior XML_Parse call that allocates the buffer internally. The over-read discloses adjacent heap memory to the calling application, recovering heap pointers, libc function pointers, and code pointers sufficient to defeat ASLR and build further exploitation primitives. |
| As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco NX-OS engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-76457 are related to out-of-bounds read issues that are grouped under the Common Weakness Enumeration (CWE) CWE-125. |
| A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to insufficient input validation of data that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API of an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a reload of the device and a DoS condition. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Use array_map_meta_equal for percpu array inner map replacement
percpu_array_map_ops.map_meta_equal points to the generic
bpf_map_meta_equal(), which does not compare max_entries. When a
percpu array serves as an inner map, replacing it with one that has
fewer max_entries bypasses the check. Since percpu_array_map_gen_lookup()
inlines the original template's index_mask as a JIT immediate, a lookup
on the replacement map can access pptrs[] out of bounds.
Point percpu_array_map_ops.map_meta_equal to array_map_meta_equal(),
which already enforces the max_entries equality check.
Add a selftest to verify that replacing a percpu array inner map with
a differently-sized one is rejected. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't offload TC setup on AP_VLAN interfaces
AP_VLAN interfaces are purely virtual, so don't try to offload
TC setup to drivers. We can't really use the AP interface either
since we may not know it all the time, and it could technically
even change.
Just reject the TC offload so things get done in software. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject dev-bound-only programs on other devices
__bpf_offload_dev_match() falls back to comparing offdev pointers after an
exact netdev mismatch. Bound-only programs normally have NULL offdevs, so
unrelated netdevs compare equal. A bound-only program on an
offload-registered netdev can instead inherit a real offdev and match a
sibling port. With CAP_BPF and CAP_NET_ADMIN, a caller can use
bpf(BPF_LINK_CREATE) with a different target ifindex to run metadata kfuncs
specialized for the bound driver on the target driver's xdp_buff. Running a
veth-bound program on tun reads beyond tun's bare stack xdp_buff as a
veth_xdp_buff.
Oops: general protection fault, probably for non-canonical address

| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix out-of-bounds read of sk_protocol in bpf_sock_destroy()
sk_protocol lives in struct sock, not in struct sock_common. A timewait
or request sock handed to bpf_sock_destroy() by the tcp iterator is
neither, so reading sk->sk_protocol runs past the object:

| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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 |
