kernel: drm/amd/display: Fix optc2_configure warning on dcn314

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix optc2configure warning on dcn314 Why dcn314 uses optc2configurecrc that wraps optc1configurecrc + set additional registers not applicable to dcn314. It's not critical but when used leads to warning like:...

kernel: drm/amd/display: fix FCLK pstate change underflow

A calculation flaw was found in the AMD display driver in the Linux kernel. When UCLK p-state is not supported, FCLK p-state change watermarks are incorrectly calculated using dummy values, potentially causing underflow. This can lead to display issues or system instability during power state...

kernel: drm: amd: display: Fix memory leakage

A memory leak flaw was found in the Linux kernel's AMD display driver in the display context construction logic. A local user can trigger this issue during AMD GPU initialization when the dcconstructctx function fails to release allocated memory in error paths. This results in permanent memory...

kernel: perf/x86/amd/core: Always clear status for idx

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/core: Always clear status for idx The variable 'status' which contains the unhandled overflow bits is not being properly masked in some cases, displaying the following warning: WARNING: CPU: 156 PID: 475601 at...

kernel: drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes WHY When PTEBufferSizeInRequests is zero, UBSAN reports the following warning because dmllog2 returns an unexpected negative value: shift exponent 4294966273 is t...

kernel: cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver

A reference leak flaw was found in the Linux kernel's AMD P-state unit test driver in the CPU policy access logic. A local user can trigger this issue by loading the amd-pstate-ut driver, which acquires CPU policy references via cpufreqcpuget without releasing them via cpufreqcpuput. This causes...

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/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: drm/amd: fix potential memory leak

A memory leak was found in the Linux kernel's AMD display driver in the clock source initialization logic. When the initialization function encounters an error in its final return path, allocated memory for the clksrc structure is not freed before returning NULL. This results in leaked memory tha...

kernel: iommu/amd: Improve page fault error reporting

A flaw was found in the Linux kernel's AMD IOMMU driver iommu/amd when handling page fault error reporting. The kernel's page fault handler for the IOMMU domain incorrectly assumed that the domain was always set up, leading to a NULL pointer dereference in the iommu/amd: Improve page fault error...
