| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Win32K allows an authorized attacker to elevate privileges locally. |
| A time-of-check time-of-use (TOCTOU) race condition combined with improper symbolic link handling in the privileged helper of TeamViewer Full Client and Host prior to version 15.83 for macOS allows a local attacker with low privileges to bypass installer package verification and install a malicious package. Successful exploitation can lead to local privilege escalation to root. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: serialize vblank counter reads against GPU reset
The vblank counter callback reads display registers and scanout
position without holding reset_domain->sem. During GPU recovery,
display commit work can call the callback while reset owns the
semaphore for writing. The hardware access then triggers the
lockdep_assert_held() in amdgpu_device_skip_hw_access() and sets
TAINT_WARN when lockdep is enabled.
Try to acquire the reset semaphore for reading before accessing the
hardware, and hold it across the counter and scanout-position reads.
If reset is already in progress, return DRM's cached software vblank
count instead. This avoids blocking behind reset and avoids accessing
display hardware while it is being reset.
The cached count is less accurate than the hardware count, but is
used only when reset prevents a safe hardware read. This addresses
the reset-time warning from this vblank path; it does not suppress or
fix unrelated lockdep warnings.

| In the Linux kernel, the following vulnerability has been resolved:
KVM: SEV: Use READ_ONCE() when reading entries/indices from PSC buffer
Use READ_ONCE() when reading entries/indices from the guest-accessible
Page State Change buffer to defend against TOCTOU bugs.
Don't bother with READ_ONCE()/WRITE_ONCE() for cases where KVM is writing
(and not consuming the result!), as the guest isn't supposed to touch the
buffer while it's being processed. I.e. using READ_ONCE() is all about
protecting against misbehaving guests. |
| In the Linux kernel, the following vulnerability has been resolved:
mailbox: imx: Add a channel shutdown field
sashiko complained about possible teardown problem. The scenario
CPU 0 CPU 1
imx_mu_isr() imx_mu_shutdown()
imx_mu_xcr_rmw(priv, IMX_MU_RCR, 0, IMX_MU_xCR_RIEn(priv->dcfg->type, cp->idx));
imx_mu_specific_rx()
imx_mu_xcr_rmw(priv, IMX_MU_RCR, IMX_MU_xCR_RIEn(priv->dcfg->type, 0), 0);
free_irq()
The RX event remains enabled because in this short window the RX event
was disabled in ->shutdown() while the interrupt was active and then
enabled again by the ISR while ->shutdown waited in free_irq().
This race requires timing and if happens can be problematic on shared
handlers if the "removed" channel triggers an interrupt. In this case
the irq-core will shutdown the interrupt with the "nobody cared"
message.
Introduce imx_mu_con_priv::shutdown to signal that the channel is
shutting down. This flag is set with the lock held (by
imx_mu_xcr_clr_shut()). The unmask side uses imx_mu_xcr_set_act() which
only enables the event if the channel has not been shutdown and
serialises on the same lock. |

| Wheels 3.0.0 through 4.1.1 can disclose detailed exceptions when allowIPBasedDebugAccess=true (disabled by default). An allowed administrator request changes error/debug-display settings in shared application scope. If it overlaps with an unauthorized client's request that raises an error, that client can receive full exception details, including tag context or a serialized exception, and any sensitive data they contain. This race does not bypass the production gate protecting developer tools. This is fixed in 4.1.2. |
| AliasVault is a privacy-first password manager with built-in email aliasing. Prior to 0.30.3, the AliasVault server API favicon extractor validates a user-supplied hostname with a first DNS lookup but allows the HTTP client to perform a second DNS lookup when connecting. An authenticated low-privileged user operating an attacker-controlled authoritative DNS server can return a public address during validation and a private address during connection, causing a publicly reachable self-hosted server to issue HTTP or HTTPS requests to internal hosts. A valid image response is returned in Base64 form, while other responses can expose limited timing and error information for internal-network reconnaissance. Exploitation requires a publicly reachable self-hosted instance with public registration enabled, an authenticated AliasVault account, an attacker-controlled authoritative DNS server, and a resolver that permits rebinding; default checks limit requests to ports 80 and 443. The browser extensions, web application, and mobile applications are not affected. This issue is fixed in version 0.30.3. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/gem: fix race between change_handle and handle_delete
drm_gem_change_handle_ioctl leaves the old handle live in the IDR
during the window between spin_unlock(table_lock) and the final
spin_lock(table_lock). A concurrent drm_gem_handle_delete on the old
handle succeeds in this window, decrements handle_count to 0, and frees
the GEM object while the new handle's IDR entry still references it.
NULL the old handle's IDR entry before dropping table_lock so that any
concurrent GEM_CLOSE on the old handle sees NULL and returns -EINVAL.
Restore the old entry on the prime-bookkeeping error path. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix amdgpu_hmm_range_get_pages
The notifier sequence must only be read once or otherwise we could work
with invalid pages.
While at it also fix the coding style, e.g. drop the pre-initialized
return value and use the common define for 2G range.

| The Espressif AES driver drivers/crypto/crypto_esp32_aes.c advertises a multi-session cipher API — it hands out up to CONFIG_ESP32_CRYPTO_AES_SESSIONS_MAX (default 4) independent sessions, each carrying its own key and direction. The AES peripheral, however, has a single chip-global set of key and mode registers, and aes_begin_session() programmed them exactly once, at session start, outside the aes_lock mutex that serialises the transforms. The per-operation handlers aes_ecb_op(), aes_cbc_op() and aes_ctr_op() then ran aes_hal_transform_block() against whatever key and direction the registers happened to hold.
As a result, once a second session is opened with a different key, every subsequent operation on the first session silently uses the second session's key and direction, and no error is reported. Because the key programming happened outside the lock, the correct usage pattern of "each thread does begin, then op, then free on its own session" also races: a second thread's cipher_begin_session() landing between the first thread's begin and its operation makes that operation run under the second thread's key. An attacker who can induce session creation on the device — for example a protocol peer whose connection causes a session key to be installed — can influence which key is resident when a victim operation runs.
The impact is a cryptographic failure rather than memory corruption: data the application believed it was protecting under one key is encrypted or decrypted under another. Where the resident key is one the attacker knows or supplied, the affected plaintext becomes recoverable by that attacker, and the operation's direction (encrypt versus decrypt) can likewise be inverted. Exposure requires an application that holds two or more concurrent sessions with different keys against this driver; no in-tree Zephyr subsystem does so today (the 802.15.4 security layer, which does open two sessions, uses CCM mode, which this driver rejects), so the risk falls on application code that uses the documented multi-session API.
The fix removes all hardware access from aes_begin_session() and reprograms the key and direction at the top of every operation, inside aes_lock, so the chip-global registers can no longer be observed stale by another session. |

| libschrift through 0.10.2 contains a divide by zero vulnerability that allows attackers to crash applications by supplying a font with unitsPerEm of 0 in the head table. Attackers can provide a crafted TrueType font whose NaN glyph coordinates bypass clip_points(), causing an out-of-bounds raster read in draw_line() during sft_render() and crashing the process. |
| Canimaan Software ClamXAV versions 3.3 - 3.11 contains a local privilege escalation vulnerability in the Privileged Helper Tool caused by a race condition and insufficient file validation, allowing a local attacker to execute arbitrary code with system privileges. Fixed in 3.11.1. |
