In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/amdgpu: fix division by zero with invalid uvd dimensions<\/p>\n
When 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.<\/p>\n
Add validation to reject frames with width < 16 or height < 16
\nbefore performing any calculations that depend on these values.<\/p>\n
V2: Format change – move up all vaiable definitions.
\nV3: Use warn_once to avoid spam.<\/p>\n
