| In the Linux kernel, the following vulnerability has been resolved:
net: ravb: serialize PTP clock teardown
ravb_ptp_interrupt() can race with ravb_ptp_stop() and pass the clock to
ptp_clock_event() while ptp_clock_unregister() is freeing it. This can
lead to a use-after-free.
Use READ_ONCE() and WRITE_ONCE() for lockless access to the clock pointer.
Atomically detach it with xchg() before disabling PTP interrupts, then
synchronize all IRQs which can invoke ravb_ptp_interrupt() before
unregistering the detached clock.
A handler which read the old pointer completes before the clock is
unregistered, while later handlers read NULL and skip the event. |
| In the Linux kernel, the following vulnerability has been resolved:
net/smc: stop killed, freed and out_of_sync sharing a byte
The three connection state flags are single-bit bitfields, so they occupy
one byte of struct smc_connection and every store to one is a
read-modify-write of the other two:
u8 killed : 1;
u8 freed : 1;
u8 out_of_sync : 1;
They are not written under a common lock. smc_cdc_msg_validate() sets
out_of_sync from the receive tasklet, while smc_conn_kill() sets killed
from process context under lock_sock(), and the receive path does not defer
to the backlog when the socket is owned -- smc_cdc_msg_recv() takes only
bh_lock_sock().
Give each flag its own byte so a store no longer touches its neighbours.
All readers test them as booleans and are unchanged. struct smc_connection
grows by two bytes. |
| 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. |
| In the Linux kernel, the following vulnerability has been resolved:
pidfd: hold exec_update_lock around namespace ioctl
The PIDFD_GET_*_NAMESPACE ioctls in pidfd_ioctl() perform a filesystem
credentials ptrace access check before handing out a namespace file
descriptor. The accompanying comment states that the code "mirrors nsfs
behavior", but, unlike the corresponding procfs paths, it does so without
holding the target task's exec_update_lock.
proc_ns_get_link() and proc_ns_readlink() both take exec_update_lock for
reading around the ptrace check and the namespace lookup, so that the
credentials used for the access decision match those of the task when its
namespace is read. Without it, a caller can pass the check against the
target's old credentials and then read the namespace after the target has
execve()'d a setuid binary and committed new credentials -- accessing
namespace information it should have been denied.
Hold exec_update_lock for reading around the ptrace check and the
namespace lookup so that pidfd truly mirrors nsfs behavior, as the comment
already claims. open_namespace() itself runs outside the lock: once a
namespace reference is obtained it carries its own refcount and is opened
with the caller's own credentials, so a concurrent execve() on the target
can no longer affect the outcome. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Replace SCX_RQ_BAL_KEEP with a dispatch verdict return
SCX_RQ_BAL_KEEP tells the pick to keep running the previous task, a leftover
from when balancing and picking were separate operations. An rq-level flag
only works while dispatches and picks pair up one to one, which core
scheduling breaks: selections interleave through dispatch's lock drops and a
pick can consume a stale flag, keeping a task that has since been dequeued.
Fixing core scheduling support requires the decision to travel with the
dispatch that made it. Make scx_dispatch_sched() and balance_one() return an
explicit verdict instead and drop the flag's plumbing from the tools autogen
enum headers.
Also factor the pick-side invocation, its follow-up queueing and the
post-dispatch checks out of do_pick_task_scx() into dispatch_pick(). No
functional changes intended.
v2: Drop the SCX_RQ_BAL_KEEP plumbing from the tools autogen enum headers
as well (Andrea). |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: lp8788-charger: fix use-after-free on remove
lp8788_charger_remove() flushes charger_work before unregistering the
IRQs. An IRQ thread can queue charger_work after flush_work() has
returned. The work can then run after devres frees pchg and dereference
it in lp8788_charger_event().
Unregister the IRQs first. free_irq() waits for any running threaded
handler, so no handler can queue more work afterwards. Then use
cancel_work_sync() to cancel pending work or wait for running work to
finish.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
timekeeping: Check the return value of tk_get_aux_ts64 in __do_adjtimex()
If the auxiliary clock is disabled during tk_get_aux_ts64() but is enabled
before tks->clock_valid is checked, then uninitialized stackdata will be
used in the calculations and indirectly leaked to userspace.
The same race window also exists after this change and also for the core
timekeeper. But in these cases the only effect would be incorrect
adjustments and this is userspace's responsibility to avoid this. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Copilot Chat (Microsoft Edge) allows an authorized attacker to disclose information over a network. |
| An authorization bypass vulnerability in LXD due to a timing flaw during configuration merging allows an authenticated attacker to bypass target project restrictions during cross-project instance copies. When copying an instance to a target project, LXD performs restriction checks before configuration merging is complete, creating a time-of-check to time-of-use (TOCTOU) condition. An attacker can exploit this flaw to copy instances with disallowed high-privilege configurations into restricted projects, bypassing security controls. |
| Path traversal in Plesk's Backup Manager causes arbitrary file write as root by an authenticated customer. |
| In the Linux kernel, the following vulnerability has been resolved:
fuse: publish io-uring queues with release semantics
fuse_uring_create_queue() initializes a fuse_ring_queue and then
publishes the pointer into ring->queues[qid] with WRITE_ONCE() under the
fch->lock. There are several readers that may concurrently be fetching
that pointer locklessly and then deferencing it.
WRITE_ONCE() doesn't ensure ordering of the queue's field
initialization before the ring->queues[qid] pointer assignment. The
queue must be published with smp_store_release() so the field
initialization is guaranteed to happen before.
Readers in paths where the read may happen concurrently with the store
need to use READ_ONCE() because any race involving a plain access is
undefined. |
| A Time-of-check Time-of-use (TOCTOU) race condition leading to insecure symlink following in Plesk causes local privilege escalation to root via arbitrary file/directory ownership takeover. |
| When guests are terminated, various pieces of cleanup need carrying out.
The cleaning up of PCI devices which were assigned to guests, and the
associated removal of tracking structures for IRQs used by the devices
occurs relatively early in the process. Unfortunately after that point
the guest about to be terminated could cause its device model (DM) to
re-establish such tracking structures, by having it bind one or more IRQs
anew. While some of those tracking structures would still be cleaned up
later on, at least one would not be. |
| PasswordPusher before 2.11.1 contains a time-of-check-to-time-of-use race condition in view limit enforcement that allows unauthenticated attackers to bypass expire_after_views limits. Attackers can send concurrent requests to the show endpoint to access one-time secrets multiple times before the view count is incremented and the push expires. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Management Instrumentation allows an authorized attacker to elevate privileges locally. |
| A security vulnerability has been detected in jofpin trape 2.0. This vulnerability affects unknown code of the file core/user.py of the component Telemetry Endpoint. Such manipulation of the argument vId leads to race condition. The attack can be executed remotely. Attacks of this nature are highly complex. It is stated that the exploitability is difficult. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet. |
| Time-of-check Time-of-use (TOCTOU) Race Condition in ZenHive mpp allows an unauthenticated remote client to redeem one confirmed on-chain payment for multiple paid-resource accesses.
The type="hash" credential path in MPP.Methods.Tempo.verify/2 guards against replay with a non-atomic check-then-mark sequence: check_hash_unused/2 reads the dedup store, an eth_getTransactionReceipt round trip verifies the payment on chain, and only then does mark_hash_used/2 write the mark. Concurrent requests carrying the same settled payment hash all pass the read before any of them writes, so each is issued a receipt. The store's atomic check_and_mark/2 primitive is available and used by the type="transaction" path, but the hash path calls plain get and put even when the configured store implements it. Exploitation requires a dedup store to be configured; the default nil store is stateless and documented as offering no replay protection at all.
This issue affects mpp: from 0.2.0 before 0.6.1. |
