CVE-2024-49904

Kernel crash via empty AMDGPU ACA list traversal

Published Oct 21, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux kernel 6.9 through 6.10.13 and 6.11 through 6.11.2 allows local users to crash systems through AMDGPU ACA handling. The aca_banks_release, aca_error_fini, and aca_manager_fini teardown routines traverse empty linked lists with list_for_each_entry_safe instead of returning before iteration, producing invalid pointer access. Reaching the flaw requires local low-privileged access and an AMD GPU corner case that leaves an ACA bank, error, or handle list empty; the reported consequence is a kernel crash.
