kernel: cpufreq: Init completion before kobject_init_and_add()

An initialization order bug was found in the Linux kernel's cpufreq subsystem during policy allocation. A local user can trigger this issue when CPU frequency policy initialization fails after kobject registration but before completion initialization, causing the cleanup path to attempt to use an...

kernel: net/sched: flower: fix filter idr initialization

A flaw was found in the Linux kernel’s networking traffic control flower classifier. The initialization of the filter IDR was moved too early in the flchange path, allowing concurrent access by multiple users while the structure was still in an inconsistent state. Under certain conditions, this...

kernel: xfrm: NULL pointer dereference in xfrm_update_ae_params()

A flaw was found in the Linux kernel’s IP framework for transforming packets XFRM subsystem. This issue may allow a malicious user with CAPNETADMIN privileges to directly dereference a NULL pointer in xfrmupdateaeparams, leading to a possible kernel crash and denial of service...

OESA-2023-1797 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds and crash in readdescriptors in drivers/usb/core/sysfs.c.CVE-2023-37453 An issue was discovered in the Linux kernel before...

OESA-2023-1799 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds and crash in readdescriptors in drivers/usb/core/sysfs.c.CVE-2023-37453 An issue was discovered in the Linux kernel before...

kernel: cpufreq: Init completion before kobject_init_and_add()

An initialization order bug was found in the Linux kernel's cpufreq subsystem during policy allocation. A local user can trigger this issue when CPU frequency policy initialization fails after kobject registration but before completion initialization, causing the cleanup path to attempt to use an...

kernel: RDMA/rxe: Fix mr->map double free

A double-free vulnerability was found in the Linux kernel RDMA RXE soft-RoCE driver's memory region handling. A local user with access to RDMA userspace verbs can register a memory region with parameters that cause initialization to fail, triggering error handling code that frees the mr-map...

kernel: wifi: ath11k: fix monitor mode bringup crash

A null pointer dereference vulnerability was found in the ath11k wireless driver in the Linux kernel. When an interface is brought up in monitor mode, the driver attempts to extract packet type from RAW monitor ring packets, which lack the expected structure. This causes a kernel crash due to...

kernel: xhci: Remove device endpoints from bandwidth list when freeing the device

A null pointer/list corruption flaw was found in the Linux kernel USB xHCI host controller code. When the xHCI host is dying or being removed, some device endpoints may remain on the software bandwidth list. Later cleanup deletes entries that were already freed, corrupting the list and crashing t...

kernel: SUNRPC: double free xprt_ctxt while still in use

A flaw was addressed in the Linux kernel’s SUNRPC implementation affecting deferred RPC request handling. When an RPC request is deferred, the internal rqxprtctxt pointer is moved from the active service request to a deferred request structure. Under certain rare conditions where a request is...

kernel: drm/i915: Fix system suspend without fbdev being initialized

A NULL pointer dereference was found in the Linux kernel Intel i915 graphics driver's framebuffer device suspend handling. On platforms without display hardware where fbdev is not initialized, a local user with privileges to initiate system suspend can trigger the suspend path, causing the driver...

kernel: nvme-tcp: don't access released socket during error recovery

A race condition leading to NULL pointer dereference was found in the Linux kernel NVMe-over-TCP driver's error recovery handling. A local user with privileges to execute NVMe management commands can run the 'nvme list' command while NVMe-over-TCP error recovery work is temporarily failing...

kernel: net/sched: flower: fix filter idr initialization

A flaw was found in the Linux kernel’s networking traffic control flower classifier. The initialization of the filter IDR was moved too early in the flchange path, allowing concurrent access by multiple users while the structure was still in an inconsistent state. Under certain conditions, this...

kernel: net: hsr: avoid possible NULL deref in skb_clone()

A flaw was found in the Linux kernel’s High-availability Seamless Redundancy HSR network subsystem. When the helper function createstrippedskbhsr returns NULL, the subsequent call to skbclone occurs without validating the returned pointer, leading to a potential NULL pointer dereference. Under...

kernel: wifi: fix potential NULL-ptr deref after clone

A flaw was found in the Linux kernel’s iwlwifi mei driver. When the driver attempts to clone a socket bufferand that operation fails, it may erroneously dereference a NULL pointer, leading to a kernel crash or denial of service. An unprivileged local user may be able to trigger this flaw by...

kernel: i40e: Fix kernel crash during reboot when adapter is in recovery mode

A flaw was found in the i40e module in the Linux kernel. When the firmware is in recovery mode during the probe phase, some probe functions are skipped, causing a NULL pointer dereference when the system shuts down or is rebooted. This issue results in a denial of service...

kernel: dm flakey: fix a crash with invalid table line

A flaw was identified in the device-mapper “dm flakey” target in the Linux kernel where invalid table line input can lead to a NULL pointer dereference. Specifically, when dmsetup is used with a malformed table line such as with the corruptbiobyte target and the argname pointer is NULL, the kerne...

kernel: ceph: fix potential use-after-free bug when trimming caps

A use-after-free vulnerability was found in the Linux kernel's Ceph filesystem client. When iterating over session caps in cephiteratesessioncaps, the session-scaplock is released temporarily, allowing another thread to remove the cap. If the cap is freed while the iteration continues, subsequent...

kernel: wifi: iwlwifi: dvm: Fix memcpy: detected field-spanning write backtrace

A vulnerability was discovered in the Intel wireless iwlwifi driver in the Linux kernel that could lead to a buffer overflow in the Driver Virtualization Module key handling code. When processing a received TKIP key that includes MIC rx/tx components, the driver did not adequately limit the amoun...

kernel: drm/bridge: it6505: Initialize AUX channel in it6505_i2c_probe

A NULL pointer dereference was found in the IT6505 DisplayPort bridge driver. If an HPD interrupt fires before the DRM bridge registration completes, the driver attempts to access an uninitialized AUX channel, causing a kernel crash...
