CVE-2024-46778

Local kernel crash via unchecked boolean pointer

Published Sep 18, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux 6.7 through 6.10.9 allows local users to crash the kernel through the AMD display driver. CalculateSwathAndDETConfiguration checks the UnboundedRequestEnabled pointer address instead of its Boolean value, so a valid pointer makes the condition true regardless of the pointed-to value and leads to an invalid dereference. A local low-privileged user must reach the affected AMD display calculation path; no confidentiality or integrity impact is reported.
