CVE-2026-31765

Summary: CVE-2026-31765 affects the Linux kernel AMDGPU driver. A mismatch between the reserved trap area (AMDGPU_VA_RESERVED_TRAP_SIZE) and the allocated KFD GPU memory on systems with 64KB pages can cause a kernel crash, including a NULL pointer dereference, when running certain GPU tests (e.g....

CVE-2026-31765 drm/amdgpu: Change AMDGPU_VA_RESERVED_TRAP_SIZE to 64KB

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Change AMDGPUVARESERVEDTRAPSIZE to 64KB Currently, AMDGPUVARESERVEDTRAPSIZE is hardcoded to 8KB, while KFDCWSRTBATMASIZE is defined as 2 PAGESIZE. On systems with 4K pages, both values match 8KB, so allocation and...
