Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is caused by page migration in the Linux kernel. When running stress-ng testing, a kernel crash occurred after a few hours due to an incorrect page mapping. The scenario...

Important: kernel

Issue Overview: A race condition between two functions, lmLogClose and txEnd, in the Linux kernel's JFS filesystem can lead to a use-after-free vulnerability and crash. CVE-2023-3397 An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO...

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: 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: 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: 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: 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: 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: 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/i915/perf: add sentinel to xehp_oa_b_counters

A bounds-checking error was found in the Linux kernel Intel i915 graphics driver's performance monitoring subsystem. A local user with access to Intel GPU performance counters can trigger address validation for observability architecture counters on Xe-HP and newer hardware, causing the driver to...

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: 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: 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...

kernel: Kernel: NULL pointer dereference in Intel GVT-g debugfs during device removal

A flaw was found in the Linux kernel's Intel GVT-g Graphics Virtualization Technology debugfs component. When a device is removed through unbinding, the intelgvtdebugfsclean function may attempt to access a debugfs root that has already been deallocated, leading to a NULL pointer dereference. A...

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...
