| 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. |
| Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in Pixelite Events Manager events-manager allows Leveraging Race Conditions.This issue affects Events Manager: from n/a through 7.4.7. |
| Use after free in Windows Universal Disk Format File System Driver (UDFS) allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows NTFS allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Active Directory Certificate Services (AD CS) allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to disclose information locally. |
| Improper access control in Microsoft Local Security Authority Server (lsasrv) allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows DCOM Server allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Composite Image File System allows an authorized attacker to elevate privileges locally. |
| Sandbox escape due to race condition in the Networking component. This vulnerability was fixed in Firefox 158, Firefox ESR 153.5, Thunderbird 158, and Thunderbird 153.5. |
| Use after free in Windows Broadcast DVR User Service allows an authorized attacker to elevate privileges locally. |
| The xHCI (USB 3) device model did not validate or save the event ring size provided by the guest. The size was re-read from guest memory on each use, and Transfer Request Block (TRB) fields were loaded without protection against concurrent modification by the guest. This race condition could be triggered by a guest running malicious, privileged code.
A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox. |
| The HDA audio device model did not check for zero-length Buffer Descriptor List (BDL) entries when starting a stream. A zero-length entry caused an out-of-bounds read or write during DMA transfer processing. BDL fields were also subject to modification by the guest after validation.
A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox. |
| The framebuffer device model's maximum resolution constants were duplicated between the framebuffer and RFB modules and had gotten out of sync. Additionally, writes to the framebuffer BAR could set arbitrary width and height values without validation, and the framebuffer BAR I/O and RFB rendering threads were not synchronized.

| In the Linux kernel, the following vulnerability has been resolved:
serial: amba-pl011: synchronize DMA teardown
dmaengine_terminate_all() does not wait for a running callback, so the TX
callback can still touch the TX buffer after it is freed. The RX poll
timer reads the RX buffers without the port lock.
Switch to dmaengine_terminate_sync() and delete the RX timer before
freeing the buffers. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: imx: Fix slave registration race and error handling
In i2c_imx_reg_slave(), the slave pointer was assigned before
pm_runtime_resume_and_get(). If pm_runtime_resume_and_get() failed,
the error path returned without clearing i2c_imx->slave, leaving it
non-NULL and causing all subsequent registration attempts to fail
with -EBUSY.
Additionally, because this driver uses a shared IRQ, the interrupt
handler i2c_imx_isr() can execute concurrently and, after acquiring
slave_lock, dereference i2c_imx->slave. The previous fix attempt
added a lockless i2c_imx->slave = NULL on the error path, but that
could race with the ISR under the lock and still cause a NULL pointer
dereference.
Fix both issues by deferring the assignment of i2c_imx->slave and
i2c_imx->last_slave_event to after a successful resume, and by
performing the assignment inside the slave_lock critical section.
This guarantees that the slave pointer is never left stale on the
error path and is always valid when observed by the interrupt handler. |
| In the Linux kernel, the following vulnerability has been resolved:
bonding: alb: re-check primary_is_promisc under RTNL in bond_alb_monitor
bond_alb_monitor() reads primary_is_promisc under RCU, then drops RCU and
takes RTNL via rtnl_trylock() before undoing the promiscuity it set on the
active slave. In that window the active slave can change under RTNL
(RTM_DELLINK -> __bond_release_one() -> bond_alb_handle_active_change()),
which already drops the promiscuity and clears primary_is_promisc. The
monitor still acts on the stale decision: if the slave was removed with no
failover, curr_active_slave is now NULL and the deref faults; if it failed
over, the stale dev_set_promiscuity(-1) underflows the new slave's
promiscuity counter and pins it in IFF_PROMISC.
Oops: general protection fault, probably for non-canonical address ...
KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]

Kernel panic - not syncing: Fatal exception
Re-check primary_is_promisc (and curr_active_slave) after taking RTNL so
the monitor only undoes an increment it still owns. The other bonding
monitors already re-read state under RTNL in their commit phase
(bond_miimon_commit/bond_ab_arp_commit); bond_alb_monitor() was the only
one acting on the pre-trylock decision. |
