CVE-2024-53108

Kernel memory read via unchecked EDID block length

Published Dec 2, 2024 · Updated Aug 5, 2026

Out-of-bounds read in Linux 6.6 AMD display code allows local users to read beyond an EDID vendor block during display discovery. amdgpu_dm_update_freesync_caps extracts a replay IEEE identifier without first confirming that amd_vsdb_block contains enough bytes. The published reproducer requires the AMDgpu display path and a short vendor-specific EDID block; KASAN records a one-byte slab over-read during device discovery.
