Description
A flaw was found in the Linux kernel's drm/amdgpu driver. The uvd/vce/vcn code accesses the Instruction Buffer (IB) without sufficient bounds checking, which could allow an attacker to trigger an out-of-bounds memory access. This vulnerability may lead to system instability or a denial of service.
