| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: validate event length before filtering
is_filtered_packet() reads the event code from skb->data[0] without first
checking that the skb is nonempty. When an opcode filter is configured,
it also reads the command opcode at offsets 3 or 4 without checking that
a Command Complete or Command Status event is long enough.
hci_send_to_sock() invokes the filter before hci_event_packet() validates
the event header. A malformed event supplied by a controller or a vhci
device can therefore cause an out-of-bounds read.
Keep the unmasked event code for the opcode checks. The masked value is
needed for the 64-bit event bitmap, but using it to identify command events
aliases event codes above 0x3f. In particular, Synchronous Train Complete
(0x4f) was treated as Command Status (0x0f) even though its payload has no
opcode.
Reject actual command events that are too short for the field being
inspected. A truncated command event cannot match a configured opcode. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: reject out-of-range OCF values
The raw HCI socket security filter has 128 OCF bits per supported OGF,
but masks the 10-bit OCF with 127 before looking up the command. An
unprivileged socket can therefore submit a reserved OCF that aliases an
allowlisted command modulo 128.
A conforming controller should reject reserved opcodes. Nevertheless,
the security decision must apply to the opcode that will actually be
sent, especially since controller-specific behavior is outside the host
stack's control.
Reject OCF values that cannot be represented by the security filter
instead of aliasing them onto an unrelated command. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: validate frame length before control and FCS access
l2cap_data_rcv() unpacks either a two-byte or four-byte control field
without first ensuring that it is present. A short ERTM or streaming-mode
frame can therefore cause an out-of-bounds read.
There is a second short-frame case when CRC16 is enabled. After the
control field is pulled, l2cap_check_fcs() subtracts two from skb->len
without checking it. If fewer than two bytes remain, the subtraction
wraps; skb_trim() leaves the buffer unchanged and the subsequent FCS
load reads past the logical end of the frame.
Validate that the frame contains both its control field and, when
enabled, its FCS before either field is accessed. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: RFCOMM: fix NULL dereference of dlc->session in RFCOMM_CONNINFO
The RFCOMM_CONNINFO getsockopt handler accepts a socket that is not
connected as long as deferred setup is enabled:
if (sk->sk_state != BT_CONNECTED &&
!rfcomm_pi(sk)->dlc->defer_setup) {
err = -ENOTCONN;
break;
}
l2cap_sk = rfcomm_pi(sk)->dlc->session->sock->sk;
dlc->defer_setup is set in rfcomm_sock_init() when rfcomm_connect_ind()
creates a child socket for an incoming connection on a listening socket
that has BT_DEFER_SETUP enabled. It is never cleared afterwards. The
session, however, can go away underneath it.
rfcomm_recv_disc() forces the dlc state before tearing it down:
d->state = BT_CLOSED;
__rfcomm_dlc_close(d, err);
The RFCOMM_DEFER_SETUP early return in __rfcomm_dlc_close() only covers
BT_CONNECT, BT_CONFIG, BT_OPEN and BT_CONNECT2, so with the state
already BT_CLOSED that switch does not match and the function falls
through to rfcomm_dlc_unlink(), which sets d->session = NULL, while
d->defer_setup stays 1.
A getsockopt(SOL_RFCOMM, RFCOMM_CONNINFO) on the accepted socket after
that point therefore skips the -ENOTCONN path -- sk->sk_state is
BT_CLOSED, but dlc->defer_setup is still set -- and dereferences the
NULL session. No race is needed: once the DISC has been processed, the
dereference is unconditional.
Reproduced on a KASAN kernel under QEMU with a BR/EDR peer emulated over
/dev/vhci: the peer brings up an ACL link, opens L2CAP on the RFCOMM
PSM, starts a session and sends SABM for a channel bound with
BT_DEFER_SETUP, and sends DISC for that dlci after the socket has been
accepted. getsockopt(SOL_RFCOMM, RFCOMM_CONNINFO) on the accepted
socket then hits:
Oops: general protection fault, probably for non-canonical address

0x10 is the offset of sock in struct rfcomm_session;
rfcomm_sock_getsockopt_old() is inlined into rfcomm_sock_getsockopt().
Commit 43a556b2fd43 ("Bluetooth: RFCOMM: take rfcomm_mutex for the
deferred setup accept") fixed the same "a remote DISC clears the session
while deferred setup is still flagged" problem in rfcomm_dlc_accept();
this is the remaining instance of it, in the getsockopt path.
Deferred setup only leaves a socket usable here once it has reached
BT_CONNECT2, so restrict the exception to that state and check that a
session is actually present before following it. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix create context out-of-bounds reads
smb2_parse_contexts() validates the complete create-context area but
does not limit each record to its Next field before dispatching it. A
malformed chain can therefore expose bytes beyond the current context to
a handler. The QFid handler also used a full response-structure cast
although it only reads DiskFileId.
The SMB2/SMB3 lease parsers made the same layout assumption: they read
LeaseState and LeaseFlags at canonical offsets rather than at
DataOffset. A valid non-canonical DataOffset could therefore yield
unrelated in-bounds data, while a short DataLength was still accepted.
Limit each context to its Next value, reject offsets before the context
header, and reject malformed chains. Bound the name range by the current
context and do not dispatch a known handler when DataLength is zero. Read
the QFid DiskFileId only when the context data covers that field. Parse the
lease context from DataOffset and require DataLength to match the v1 or v2
lease_context size used by ksmbd. A size mismatch skips lease parsing
without failing the open. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: close handle after create-context parsing failure
SMB2_open() accounts a successful CREATE response as a remote open before
parsing its create contexts. If smb2_parse_contexts() rejects malformed
context data, SMB2_open() returns without closing the handle, leaving the
server-side handle open and num_remote_opens elevated.
Close the handle after a post-CREATE context parsing failure so the error
path releases the remote resource and balances the open count. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: use finish_no_open() for non-regular inodes
An O_CREAT open can find an existing symlink or another non-regular
inode. cifs_atomic_open() calls finish_open() on it and attaches a
cifsFileInfo. Symlink inodes have no CIFS release operation, so the
dentry reference held by cifsFileInfo is leaked. FMODE_OPENED also
prevents the VFS from following the symlink.
Track whether cifs_do_create() returned an open server handle. For
non-regular inodes, close the handle if present, remove the pending
open, and call finish_no_open() so the VFS can continue the lookup.
Do not set FMODE_CREATED unless a regular file was opened. For
O_NOFOLLOW with __O_REGULAR, return -ELOOP before the VFS's
-EFTYPE check.
Defer closing a legacy POSIX handle on a non-regular inode until
after inode lookup. This avoids closing it again if lookup fails. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: close completed creates on compound wait errors
compound_send_recv() waits for responses in order. If a later wait is
interrupted, or if a later MID fails during response synchronization, an
earlier CREATE may already have opened a remote handle. The earlier mid
is then released without invoking handle_cancelled_mid(), leaving the
remote handle open because no FID was copied to the caller.
Mark completed earlier mids as cancelled when a compound wait or MID
synchronization aborts. Keep their response buffers attached while the
MIDs are synchronized, and transfer them only after synchronization of
the processed responses, so the release path can inspect successful
CREATE responses and queue SMB2_close() after a later failure. Account for
a remote open only after the close work is allocated and before it is
queued, since the caller has not yet updated num_remote_opens. Mark the
create+close compound used by smb2_unlink() so it is not closed again.
Non-CREATE responses and compounds that already include a close keep their
existing behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: delete compound mids on send failure before unlock
When sending a compound request fails, smb_send_rqst() kicks off a
reconnect. compound_send_recv() still has those mids on pending_mid_q,
but it unlocks the server without removing them first.
During reconnect, cifs_abort_connection() walks pending_mid_q and runs
each mid callback. With no response yet, those callbacks return credits
and drop in_flight. Then compound_send_recv()'s send-error path returns
the same credits again. in_flight ends up decremented twice and
smb2_add_credits() WARNs.
syzbot hits this during SMB2_negotiate when the socket send fails.
cifs_call_async() already calls delete_mid() before unlock on send
failure. Do the same for compound chains and set cancelled_mid[] so the
out: path does not delete them again. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: release orphanage dir inode if chown fails
LOLLM points out that we leak the igrab'd reference to the orphanage
directory inode if chowning it fails. Fix that. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: fix wild memcpy access when formatting ondisk rtrefcount btree roots
LOLLM noticed that the inode btree root formatting methods copy too many
bytes -- there's only one set of keys in node blocks, not two. This
causes memory corruption of whatever's beyond the buffers. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: don't let memory failures leak blocks and kill repairs
LOLLM complains that a memory allocation failure in
xrep_newbt_add_blocks results in online repair leaking blocks that were
previously allocated to write a new btree, but the problem is worse than
that -- a limitation of the codebase is that the callers cannot undo the
transaction /and/ return the error -- either you undo all changes and
commit the transaction, or you error out and the filesystem goes down.
However, the new btree space reservation object isn't that big (~48
bytes). Let's just do a NOFAIL allocation and the problem goes away. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: drop dquot flush lock when we can't find a buffer to flush
LOLLM noticed that xfs_qm_flush_one fails to drop the dquot flush lock
if it can't grab the buffer associated with the dquot. Since there's no
buffer, nobody else is going to drop the dqflock, so we need to do it
ourselves. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: PPC: Book3S HV: fix secure device page leak on uv_page_in() failure
In kvmppc_svm_page_in(), if uv_page_in() fails after
kvmppc_uvmem_get_page() has succeeded, the secure device page is never
released. kvmppc_uvmem_get_page() sets a bit in kvmppc_uvmem_bitmap,
allocates a kvmppc_uvmem_page_pvt struct, marks the GFN as
KVMPPC_GFN_UVMEM_PFN, and calls zone_device_page_init() which sets
refcount=1 and locks the page. The subsequent goto out_finalize skips
the *mig.dst assignment, so migrate_vma_finalize() is a no-op for the
page, and none of those resources are ever reclaimed.
Each occurrence permanently consumes one entry from the firmware-bounded
secure memory pool (kvmppc_uvmem_bitmap), leaks pvt, and leaves the GFN
marked as secure — making it unusable for the lifetime of the VM.
The twin __kvmppc_svm_page_out() already handles the analogous uv_page_out()
failure correctly with unlock_page(dpage); __free_page(dpage). Apply
the same pattern here: unlock_page() followed by put_page(), which
chains through free_zone_device_folio() into kvmppc_uvmem_folio_free()
to clear the bitmap bit, free pvt, and reset the GFN state.
Reachable whenever uv_page_in() returns an error (e.g. UV pool
exhaustion) on any POWER9/10 + Ultravisor/PEF system. |
| The ElementsReady Addons for Elementor WordPress plugin through 6.7.2 does not perform authorization checks that halt execution in several of its settings-save handlers, allowing users with subscriber-level access and above to overwrite the ElementsReady Addons for Elementor WordPress plugin through 6.7.2's stored settings, including its stored API credentials and its feature and template configuration. |
| The iPOSpays Payment Gateway for WooCommerce WordPress plugin before 1.4.7 does not verify that a payment was actually completed before recording an order as paid, allowing unauthenticated users to mark any unpaid order as paid and to rewrite its total. |
| The Blaze Demo Importer WordPress plugin before 1.0.17 does not sanitize uploaded SVG files and registers the SVG MIME type for the WordPress media library unconditionally, allowing authenticated users with the Author role or higher to upload a crafted SVG that executes arbitrary JavaScript in the browser of any user who opens the file. |
| A flaw has been found in eremef bandcamp-player up to 1.8.33-beta. The impacted element is an unknown function of the file database.ts of the component Remote Control Server. Executing a manipulation of the argument remoteEnabled can lead to missing authentication. The attack may be launched remotely. Upgrading to version 1.8.34-beta is sufficient to resolve this issue. This patch is called ccba99b66bc61acf46e4a332034799d7452ddea6. Upgrading the affected component is advised. |
| The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.74.3 via the get_instance_css function. This makes it possible for authenticated attackers, with contributor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The widget's normal update()/sanitize_field_input() pipeline — which would reject non-hex color values — is bypassed entirely because the [siteorigin_widget] shortcode handler calls $the_widget->widget() directly on the attacker-supplied decoded JSON instance. |
| The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.9 This is due to a missing ownership and capability check on the `user` parameter within the `process_edit()` function, which allows any authenticated user with the `edit_contacts` capability to reassign a contact record's linked WordPress user ID to any arbitrary account without requiring the `edit_users` or `promote_users` capabilities. This makes it possible for authenticated attackers, with sales_rep-level access and above, to escalate their privileges to administrator by linking a contact to an administrator's WordPress user ID, then creating a note containing the `{auto_login_link}` replacement tag to trigger generation of a valid auto-login permissions-key URL for the administrator-linked contact, and finally visiting that URL to authenticate as the targeted administrator. The auto-login URL is stored in the note content and is readable back by the attacker via the `view_notes` and `add_notes` capabilities that the sales_rep role holds by default. |
