CVE-2024-53199

Kernel crash via unchecked allocation failure

Published Dec 27, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux 6.11 allows local users to crash the kernel by triggering an allocation failure during i.MX AUDMIX probe. The imx_audmix_probe function fails to test the devm_kasprintf return value before dereferencing the failed allocation. Reachability requires low-privileged local access, allocation failure during probe, and hardware using the NXP i.MX AUDMIX driver; the documented consequence is a kernel crash.
