CVE-2024-42122

Kernel crash via unchecked display allocations

Published Jul 30, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux kernels starting with 4.15 allows local users to crash the kernel during AMD display setup. AMD display clock-manager and resource-construction paths use structures returned by kzalloc without first rejecting NULL allocation results. Triggering requires local low-privilege access, an affected AMD display path, and a failed allocation; the consequence is a kernel crash.
