kernel: amdgpu/pm: prevent array underflow in vega20_odn_edit_dpm_table()

An array underflow vulnerability was found in the Linux kernel's AMD GPU power management driver. In vega20odneditdpmtable, the inputindex variable is validated to be at most 2 but is not checked for negative values. Since this value is user-controlled via sysfs, a user can provide a negative val...

kernel: drm/amdgpu: Fix call trace warning and hang when removing amdgpu device

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix call trace warning and hang when removing amdgpu device On GPUs with RAS enabled, below call trace and hang are observed when shutting down device. v2: use DRM device unplugged flag instead of shutdown flag as the...

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: Linux kernel: Resource exhaustion in amdgpu due to PCI device reference count leak

A flaw was found in the Linux kernel's drm/amdgpu component. A missing call to pcidevput in the amdgpuatrmgetbios function leads to a PCI device reference count leak. A local attacker could exploit this to cause resource exhaustion, potentially resulting in a Denial of Service DoS...

kernel: drm/amdgpu: Fix size validation for non-exclusive domains (v4)

A NULL pointer dereference flaw was found in the Linux kernel's AMD GPU driver in the buffer object size validation logic. A local user on systems with AMD graphics hardware can trigger this issue by requesting memory allocation in non-exclusive domains when the Translation Table Manager domain...

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: drm/amdkfd: Fix double release compute pasid

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix double release compute pasid If kfdprocessdeviceinitvm returns failure after vm is converted to compute vm and vm-pasid set to compute pasid, KFD will not take pdd-drmfile reference. As a result, drm close file...

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: drm/amdkfd: Fix memory leakage

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix memory leakage This patch fixes potential memory leakage and seg fault in gpuvmimportdmabuf function...

kernel: drm/amdkfd: Fix kernel warning during topology setup

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix kernel warning during topology setup This patch fixes the following kernel warning seen during driver load by correctly initializing the p2plink attr before creating the sysfs file: +0.002865 ------------ cut here...

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,...
