In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Fix null-ptr-deref in vkmsrelease A null-ptr-deref is triggered when it tries to destroy the workqueue in vkms-output.composerworkq in vkmsrelease. KASAN: null-ptr-deref in range 0x0000000000000118-0x000000000000011f CP...

kernel: use-after-free during a race condition between a nonblocking atomic commit and a driver unload in drivers/gpu/drm/drm_atomic.c

A flaw was found in the Linux kernel Direct Rendering Infrastructure DRI subsystem in which a use-after-free can be caused when a user triggers a race condition between a nonblocking atomic commit and a driver unload. A local user could use this flaw to crash the system or potentially escalate...

kernel: Linux kernel: Denial of Service due to PCI device reference count leak

A flaw was found in the Linux kernel. A local low-privileged user could exploit a reference count leak in the drm/amdgpu component. This vulnerability, related to how PCI Peripheral Component Interconnect devices are managed, could lead to a Denial of Service DoS by exhausting system resources...

kernel: Linux kernel: NULL pointer dereference in drm/amdkfd leads to Denial of Service

A flaw was found in the Linux kernel. A local user could trigger a NULL pointer dereference within the drm/amdkfd component during error handling in the kfdprocessdeviceinitvm function. This vulnerability, a type of memory corruption, can lead to a system crash. Successful exploitation results in...

kernel: vmwgfx: use-after-free in vmw_execbuf_tie_context

A use-after-free vulnerability was found in the Linux kernel's vmwgfx driver in vmwexecbuftiecontext. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, who can issue an ioctl on the resulting file descriptor, to crash the system, causin...

kernel: drm/ttm: Fix a NULL pointer dereference

In the Linux kernel, the following vulnerability has been resolved: drm/ttm: Fix a NULL pointer dereference The LRU mechanism may look up a resource in the process of being removed from an object. The locking rules here are a bit unclear but it looks currently like res-bo assignment is protected ...

kernel: drm/amdkfd: Fix an illegal memory access

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix an illegal memory access In the kfdwaitonevents function, the kfdeventwaiter structure is allocated by alloceventwaiters, but the event field of the waiter structure is not initialized; When copyfromuser fails in...

kernel: drm/amdgpu/powerplay/psm: Fix memory leak in power state init

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/powerplay/psm: Fix memory leak in power state init Commit 902bc65de0b3 "drm/amdgpu/powerplay/psm: return an error in power state init" made the power state init function return early in case of failure to get an entry...

kernel: null pointer when load rlc firmware

A vulnerability was found in the drm/amdgpu driver of Linux Kernel, causing null pointer dereference when attempting to load RLC Run-Length Coding firmware. This issue arises if the firmware has an incorrect header size, causing premature release of the firmware pointer in amdgpuucoderequest,...

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: vmwgfx: use-after-free in vmw_cmd_res_check

A use-after-free vulnerability was found in the Linux kernel's vmwgfx driver in vmwcmdrescheck. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, who can issue an ioctl on the resulting file descriptor, to crash the system, causing a...

kernel: drm/amdgpu: SDMA update use unlocked iterator

A denial of service exists in the linux kernel such that there is a SDMA update page table may be called from an unlocked context, leading to damage to system availability and integrity...

kernel: Linux kernel: Denial of Service and information disclosure via undefined bit shift in drm/ttm

A flaw was found in the Linux kernel's drm/ttm component. A local user could exploit an undefined behavior in bit shifting, specifically when a signed 32-bit value is shifted by 31 bits, which cannot be represented in an 'int' type. This vulnerability could lead to local information disclosure,...
