kernel: scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add()

In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Fix possible resource leaks in mpt3sastransportportadd In mpt3sastransportportadd, if sasrphyadd returns error, sasrphyfree needs be called to free the resource allocated in sasenddevicealloc. Otherwise a kernel...

kernel: RDMA/core: Make sure "ib_port" is valid when access sysfs node

A NULL pointer dereference flaw was found in the Linux kernel RDMA core's sysfs handling. A local user with access to InfiniBand sysfs nodes can read sysfs attributes while an InfiniBand port is being removed, causing the kernel to dereference a NULL ibport pointer when the port structure has bee...

kernel: udmabuf: Set ubuf->sg = NULL if the creation of sg table fails

A flaw was found in the Linux kernel’s udmabuf subsystem where the scatter-gather sg pointer was not properly set to NULL if creation of the sg table failed. If userspace attempts to map a dmabuf and the sg table allocation fails e.g., due to memory exhaustion, the kernel later attempts to free a...

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: 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...

kernel: drm/amdgpu: Fix type of second parameter in odn_edit_dpm_table() callback

A function prototype mismatch was found in the AMD GPU driver's DPM table callbacks. When kCFI Control Flow Integrity is enabled, the mismatched types cause CFI validation failures, potentially crashing the kernel...

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: Linux kernel: Denial of Service in vmwgfx due to invalid DMA surface copies

A flaw was discovered in the Linux kernel’s DRM vmwgfx driver related to how cursor images are snooped and copied. When the dimensions of a DMA surface copybox were derived from untrusted userspace data without proper validation against the expected snooped cursor size, an invalid size could caus...

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: 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: 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: 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: 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: 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: 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...
