  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: fix division by zero with invalid uvd dimensions\n\nWhen width or height is less than 16, width_in_mb or height_in_mb\nbecomes 0, leading to fs_in_mb being 0. This causes a division by\nzero when calculating num_dpb_buffer in H264 and H264 Perf decode\npaths.\n\nAdd validation to reject frames with width \u003c 16 or height \u003c 16\nbefore performing any calculations that depend on these values.\n\nV2: Format change - move up all vaiable definitions.\nV3: Use warn_once to avoid spam.\n\n(cherry picked from commit 3e41d26c70b0a459d041cc19482a226c4b7423cb)",
