CVE-2026-68281

The CVE-2026-68281 entry covers the Linux kernel DRM/imagination driver where the DRM scheduler’s prepare_job() previously failed to account for the dependency between paired geometry and fragment jobs. The fix updates job_count_remaining_native_deps() so that paired job fences are counted as dep...
