| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: validate individual TWT params before driver setup
ieee80211_process_rx_twt_action() only partially validates a received
S1G TWT setup frame before queueing it.
An individual agreement can therefore reach ieee80211_s1g_rx_twt_setup()
with twt->length too short for the full struct ieee80211_twt_params.
The individual path passes twt to drv_add_twt_setup(). Both the tracepoint
and the driver callback consume the complete parameters block, not merely
req_type. Do not pass a short individual agreement to the driver.
Broadcast agreements remain unchanged because they are rejected locally
after accessing only req_type.
[edit commit message to not overclaim lack of validation nor
understate driver impact] |
| In the Linux kernel, the following vulnerability has been resolved:
of: reserved_mem: prevent OOB when too many dynamic regions are defined
On boot, fdt_scan_reserved_mem() saves each dynamically-placed
/reserved-memory subnode into a local array of size
MAX_RESERVED_REGIONS.
If the device tree defines more than MAX_RESERVED_REGIONS
dynamically-placed regions, fdt_scan_reserved_mem() writes past the
end of the local array.
Add a bounds check that logs an error and skips the excess regions,
restoring the original behavior. |
| The SmartAIPress WordPress plugin through 1.2.0 does not perform a capability check on one of its AJAX actions and does not validate a user-supplied URL before fetching it server-side, allowing users with subscriber-level access and above to make the site retrieve arbitrary internal or external URLs and read the response, resulting in a full-read Server-Side Request Forgery. |
| The Catfolders Document Gallery Pro WordPress plugin before 2.0.7 does not authorise some of its REST API routes, and the token identifying the requested content is forgeable client side, allowing unauthenticated users to list and download the contents of folders that were never published on the site. |
| The HEL Online Classroom: AI-powered Online Classrooms WordPress plugin through 1.0.3 does not have any authorisation or authentication check when saving its settings, allowing unauthenticated users to overwrite them and repoint every online classroom, along with the shared secret those sessions are signed with, at infrastructure of their choosing. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/userptr: Hold notifier_lock for write on inject test path
When CONFIG_DRM_XE_USERPTR_INVAL_INJECT=y, xe_pt_svm_userptr_pre_commit()
runs vma_check_userptr() with the svm notifier_lock taken for read. The
test injection causes vma_check_userptr() to call
xe_vma_userptr_force_invalidate(), which feeds into
xe_vma_userptr_do_inval() with drm_gpusvm_ctx.in_notifier=true. That
flag tells drm_gpusvm_unmap_pages() the caller already holds
notifier_lock for write and only asserts the mode. Because the caller
actually holds it for read, the assertion fires:

| In the Linux kernel, the following vulnerability has been resolved:
net: dst_metadata: fix false-positive memcpy overflow in tun_dst_unclone
kmalloc_flex() in metadata_dst_alloc() sets __counted_by for the
structure to the options_len, which is then initialized to zero.
Later, we're initializing the structure by copying the tunnel info
together with the options, and this triggers a warning for a potential
memcpy overflow, since the compiler estimates that the options can't
fit into the structure, even though the memory for them is actually
allocated.
memcpy: detected buffer overflow: 104 byte write of buffer size 96
WARNING: CPU: X PID: Y at lib/string_helpers.c:1036 __fortify_report
skb_tunnel_info_unclone+0x179/0x190
geneve_xmit+0x7fe/0xe00
The issue is triggered when built with clang and source fortification.
Fix that by doing the copy in two stages: first - the main data with
the options_len, then the options. This way the correct length should
be known at the time of the copy.
It would be better if the options_len never changed after allocation,
but the allocation code is a little separate from the initialization
and it would be awkward and potentially dangerous to return a struct
with options_len set to a non-zero value from the metadata_dst_alloc().
Another option would be to use ip_tunnel_info_opts_set(), but it is
doing too many unnecessary operations for the use case here. |

ALSA: seq: oss: Serialize readq reset state with q->lock
snd_seq_oss_readq_clear() resets qlen, head, and tail without
q->lock even though the normal reader and producer paths serialize the
same ring state under that spinlock. A reset can therefore race
snd_seq_oss_readq_free() or snd_seq_oss_readq_put_event() and leave
stale records in the queue, drop freshly queued ones, or report the
wrong readiness after wakeup. KCSAN reports a data race between
snd_seq_oss_readq_clear() and snd_seq_oss_readq_free().
Take q->lock while clearing the ring and resetting input_time. Factor
the enqueue logic into a caller-locked helper so
snd_seq_oss_readq_put_timestamp() updates its suppression state under
the same lock instead of racing the reset path.
The buggy scenario involves two paths, with each column showing the
order within that path:
reset path: locked readq updater:
1. snd_seq_oss_reset() or 1. A reader or callback producer
release reaches takes q->lock on the same queue.

net/sched: sch_fq_codel: Do not call qdisc_tree_reduce_backlog during peek before restoring qlen
Whenever fq_codel drops packets during peek, it calls
qdisc_tree_reduce_backlog. An issue arises because it calls
qdisc_tree_reduce_backlog before it reincrements the qlen. If qlen drops
to zero, but peek returns an skb, the parent's qlen_notify callback will be
executed even though fq_codel still has 1 packet on the queue and, thus,
will mistakenly deactivate the parent's class causing issues like a recent
report [1] and a wild memory access in qfq:

| In the Linux kernel, the following vulnerability has been resolved:
btrfs: lzo: reject compressed segment that overflows the compressed input
lzo_decompress_bio() validates each on-disk segment length seg_len only
against the workspace cbuf size, not against the compressed input size
(compressed_len, the total folio bytes of the bio). A crafted extent can
carry a segment whose seg_len passes the cbuf check but runs past the end
of the bio, so copy_compressed_segment() walks off the last folio:
get_current_folio() then returns the NULL folio from bio_next_folio(), and
with CONFIG_BTRFS_ASSERT disabled (default) folio_size(NULL) faults.

sctp: validate Adaptation Indication parameter length
The Adaptation Layer Indication parameter contains a fixed 32-bit
Adaptation Code Point after its parameter header. However,
sctp_verify_param() accepts a header-only parameter because the generic
parameter walker only requires the header to be present.
sctp_process_param() then reads adaptation_ind beyond the declared
parameter. When the malformed parameter is last in an INIT, the read
starts at the receive skb tail, and the value is copied into the state
cookie returned in the INIT ACK. This may disclose four receive-buffer
tail bytes.
Require the declared parameter length to match the fixed structure size
and abort the association through the existing invalid parameter length
path otherwise. |
| The Booking for Appointments and Events Calendar WordPress plugin before 2.4.9 does not check that a user holds the required capability before letting them change an appointment's status, allowing customers to set arbitrary statuses on appointments they are booked on, including approving their own bookings that were left awaiting approval and overwriting another customer's booking status on a shared appointment. |
| The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.43 does not validate a redirect parameter supplied during user registration before using it, allowing unauthenticated attackers to redirect users to arbitrary external URLs. |
| The Rank Math SEO WordPress plugin before 1.0.277 does not check that the user requesting an automated SEO fix holds the capability WordPress itself requires for the settings being changed, allowing users with the Editor role to modify site-wide core WordPress settings that are reserved to administrators. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: flowtable: avoid num_encaps underflow on bridge VLAN untag
The DEV_PATH_BR_VLAN_UNTAG case post-decrements info->num_encaps
inside WARN_ON_ONCE(). num_encaps is u8, so if it's already 0 the
decrement still happens and wraps it to 255. The break only leaves
the inner switch -- a later path entry can set info->indev back to
a real device, and we end up returning with num_encaps == 255.
nft_dev_forward_path() then walks info.encap[] (size 2) up to
num_encaps, which means an OOB stack read and a bogus count copied
into the route descriptor.
Should only happen on a malformed bridge path stack, hence the WARN,
but worth handling sanely. Move the decrement out of the WARN.
[ While at this, remove the WARN_ON_ONCE since this can only happen
with a buggy bridge path stack --pablo ]. |
| The MemberHero WordPress plugin through 6.9 does not restrict which account fields can be supplied during its frontend registration process, allowing unauthenticated attackers to register a new user with an arbitrary role, including Administrator, leading to a full site takeover.
Version 6.9 is advertised as resolving this issue, but the fix is incomplete and the current version remains exploitable by unauthenticated attackers to obtain administrator access and to take over existing accounts. No version that fully addresses the issue is available at the time of this advisory.
Mitigation: deactivate and remove the MemberHero WordPress plugin through 6.9 until a version that fully resolves this issue is released. If the MemberHero WordPress plugin through 6.9 must stay active, disable public registration, restrict access to the registration functionality, and monitor the site for unexpected administrator accounts. |
| The Total processing card payments for WooCommerce WordPress plugin through 7.3 does not validate a user-supplied path before using it to build a server-side verification request, and does not verify the authenticity of the response, allowing unauthenticated attackers to redirect that request to an arbitrary host (disclosing the merchant's payment-gateway credentials) and to forge a success response that marks arbitrary WooCommerce orders as paid. |
| The Newsletters WordPress plugin before 4.17 does not generate its API key using a sufficiently random source, deriving it from a publicly known value, allowing unauthenticated attackers to compute the key and perform privileged actions such as adding and deleting subscribers and sending emails, when the optional API has been enabled. |
| The Newsletters WordPress plugin before 4.17 does not perform any nonce or capability check when saving one of its settings screens, and writes every submitted parameter into its own options, allowing attackers to make a logged in administrator overwrite arbitrary Newsletters WordPress plugin before 4.17 settings, including the credential protecting its API, via a Cross-Site Request Forgery attack. |
| The MStore API WordPress plugin before 4.21.1 does not verify that the order targeted by one of its delivery endpoints belongs to the requester, allowing any authenticated user, including Subscribers, to mark arbitrary orders as completed and paid without any payment being made. |
