| In the Linux kernel, the following vulnerability has been resolved:
batman-adv: dat: atomically update mac addresses
When a MAC address is updated in batadv_dat_entry_add(), it is done using a
simple copy function. A parallel reader might only see parts of this
update. In worst case, the reader is transporting the half updated MAC
address over the network or is creating an ARP response using it -
poisoning the ARP cache.
atomic64_t can be used to store the 48 bit of a mac address. A reader will
then either see the old mac address or the new one - never a mixture of
both. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme: add missing SRCU grace period in error path
nvme_alloc_ns() error path at out_unlink_ns removes ns from the
namespace head siblings list with list_del_rcu(&ns->siblings) but
does not wait for SRCU readers before freeing the namespace struct.
Multipath code iterates the head->list under srcu_read_lock() in
nvme_find_path() and nvme_mpath_revalidate_paths(), so a concurrent
reader can still hold a reference to ns when kfree(ns) runs.
The normal removal path in nvme_ns_remove() correctly calls
synchronize_srcu(&ns->head->srcu) after list_del_rcu() to wait for
in-progress readers. Add the same grace period in the error path. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix race between sctp_wait_for_connect and peeloff
sctp_wait_for_connect() drops and re-acquires the socket lock while
waiting for the association to reach ESTABLISHED state. During this
window, another thread can peeloff the association to a new socket via
getsockopt(SCTP_SOCKOPT_PEELOFF), changing asoc->base.sk. After
re-acquiring the old socket lock, sctp_wait_for_connect() returns
success without noticing the migration — the caller then accesses
the association under the wrong lock in sctp_datamsg_from_user().
Add the same sk != asoc->base.sk check that sctp_wait_for_sndbuf()
already has, returning an error if the association was migrated while
we slept. |
| Race condition in Transactions Platform in Google Chrome prior to 154.0.8037.57 allowed a remote attacker to potentially leak sensitive information via a crafted HTML page. (Chromium security severity: Medium) |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: safely drain sessions during logoff
SMB3 multichannel allows requests for one session to run on multiple
connections. Wait for all channels bound to a session before freeing
shared session objects.
A deferred byte-range lock remains counted as a running request and only
wakes when its file closes. Wake blocked locks during the drain without
unpublishing or modifying their file objects. Synchronous CANCEL requests
must invoke their cancellation callback to wake pending operations, while
CHANGE_NOTIFY completion remains specific to the asynchronous path.
Serialize session teardown with channel registration and previous-session
cleanup, and use atomic work-state transitions so LOGOFF, CANCEL, and
connection teardown invoke cancellation callbacks only once. |
| Podgrab contains an unauthenticated denial-of-service vulnerability caused by unsynchronized concurrent access to shared maps (activePlayers and allConnections) in its WebSocket handler, where Wshandler and HandleWebsocketMessages goroutines read and write these maps without a mutex. A remote attacker can open multiple WebSocket connections to the /ws endpoint and send messages in a loop to trigger a Go runtime data race that crashes the process, causing a denial of service that requires operator intervention to restore service. |
| MISP contains a vulnerability in its one-time password (OTP) authentication flow that allows replay of a consumed HOTP (paper) token and rewinding of the token counter.
The HOTP verification logic compared the submitted token against a counter value that was cached in the user's session at the time the password was entered, rather than against the authoritative counter stored in the database. Because the session-cached counter is not updated after a token is successfully consumed, an attacker who holds a valid session (password already submitted) can reuse a previously burned HOTP token. The stale cached counter still matches the replayed token, granting a second successful authentication and effectively rewinding the counter state.
Preconditions:
- The target user has HOTP (paper token) second-factor authentication enabled.
- The attacker possesses a valid session in which the password step has already been completed (the OTP step is pending).
- The attacker has access to at least one HOTP token value (e.g., a paper token list).
Security impact:
- Bypass of the second authentication factor, allowing unauthorized access to a user's MISP account.
- Corruption of the HOTP counter state, potentially invalidating subsequent legitimate tokens or enabling further replays.
Affected versions: <2.5.48. |
| Ghost versions 0.5.0 before 6.23.0 contain a concurrency issue in the staff invitation acceptance mechanism that allows multiple accounts to be created from a single invite token. Attackers can exploit this race condition by submitting concurrent requests with the same invitation token to create duplicate user accounts. |
| Race condition, use-after-free in the Audio/Video component. This vulnerability was fixed in Thunderbird 157 and Firefox 157. |
| NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where a privileged user could trigger a race condition that leads to an out-of-bounds write. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering. |
| Race condition in V8 in Google Chrome prior to 154.0.8037.57 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High) |
| Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacker with monitoring access can exploit this issue to cause incorrect data processing or a denial-of-service condition. |
| A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process. |
| The account recovery (password reset) functionality in the vulnerability-lookup web application contains a time-of-check-to-time-of-use (TOCTOU) race condition in the consumption of single-use recovery tokens. The original implementation verified the token nonce against the stored digest and then consumed (cleared) it in separate database operations. Two concurrent HTTP requests presenting the same valid recovery token could both pass the verification check before either transaction committed, allowing both to set their own password on the target account. The last transaction to commit overwrites the first, enabling an attacker who possesses a valid recovery token to replace the legitimate user's password with one of their choosing.
A secondary defect in the same endpoint (confirm_account) allowed a valid recovery link to be used to set an empty or trivially short password (e.g., three characters). The view handler performed only a manual equality comparison between the two password fields and never invoked the form's validation logic, bypassing the intended minimum-length and complexity constraints.
The affected component is the user account recovery endpoint (/user/confirm_account/<token>) and the associated token verification and consumption logic in the User model (website/models/user.py) and the view layer (website/web/views/user.py). |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Management Instrumentation allows an authorized attacker to elevate privileges locally. |
| OpenClaw (npm package `openclaw`) versions >= 2026.7.2 and < 2026.9.2 contain a race condition in the Discord realtime voice transcript path. Concurrent control-classified voice transcripts could consume speaker context belonging to another participant after an asynchronous control check, causing a transcript to inherit another speaker's owner status. In Discord agent-proxy voice sessions using the affected realtime control path, an utterance from a non-owner participant could reach the downstream agent boundary marked as owner, so owner-sensitive behavior is applied to the wrong speaker. Exploitation depends on concurrent transcript timing and on the tools and commands available to the affected agent. The issue is fixed in 2026.9.2; as a workaround, disable Discord realtime voice for agents that distinguish owner and non-owner senders. |
| GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.6 before 19.2.7, 19.3 before 19.3.3, and 19.4 before 19.4.1 that under a race condition, the MCP search tool's shared state handling could have caused search results to be returned under an incorrect user context. |
| In the Linux kernel, the following vulnerability has been resolved:
coresight: perf: Retrieve path and source from event data
ETM perf callbacks currently use the per-CPU csdev_src pointer, which
can race with updates during device registration and unregistration.
The AUX setup already builds and stores the path in the event data.
Use this path to retrieve the source instead of csdev_src to avoid
the race.
Export coresight_get_source() and add etm_event_get_ctxt_path() to
retrieve the context's path and its source with READ_ONCE() /
WRITE_ONCE() accessors. Give the comments to explain why this
approach is safe when pause or resume callbacks preempt the disable
callback (e.g. via NMI). |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Keep kick_sync waiting on the rq's own CPU
kick_sync_wait_bal_cb() assumes it runs on the rq's CPU from the
__schedule() tail: the snapshots it compares against live in that CPU's
percpu area and the busy-wait runs with the rq lock dropped and IRQs
enabled.
However, dispatch can now drop the rq lock while the callback sits queued,
and rq lock takers in that window (the sched class change paths, the scx
task iterator) flush pending balance callbacks on release, running the
callback on a foreign CPU. Such a run compares against unrelated snapshots
and can deadlock when the executing CPU is itself a wait target.
Bail on a foreign CPU and leave the wait state alone. The wait only observes
progress that the resched kicks already guarantee and the rq's next wait
picks up the stale cpus_to_sync bits. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/page_owner: use memcg_data snapshot to avoid TOCTOU in print_page_owner_memcg()
print_page_owner_memcg() reads page->memcg_data via READ_ONCE() at the
start to guard against tail pages and NULL data. However, it later
re-reads page->memcg_data locklessly in two places:
1: page_memcg_check(page)
2: PageMemcgKmem(page) (via folio_memcg_kmem(), which includes
VM_BUG_ON assertions for tail pages and MEMCG_DATA_OBJEXTS)
If the page is concurrently freed and reallocated as a THP tail page or
slab page between these calls, the VM_BUG_ON assertions can trigger on
CONFIG_DEBUG_VM=y builds, crashing the kernel.
Fix both TOCTOU issues by using the memcg_data snapshot throughout. |
