Local slab-data disclosure via uncleared EDID buffer
Published May 2, 2025 · Updated May 11, 2026
Information disclosure in Linux 6.2 through 6.2.7 and 6.3-rc1 through 6.3-rc2 allows local users to read slab data from logs. The panel-ID fetch path in drivers/gpu/drm/drm_edid.c does not clear its transfer buffer before an EDID read, so failures that leave it unchanged log stale slab contents. Exploitation requires local low-privileged access and a failed EDID fetch; the reported consequence is disclosure through kernel logs.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
