CVE-2024-42089

Local system crash via uninitialized device pointer

Published Jul 29, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux kernel 3.18 and later before branch-specific fixes allows local users to crash the system during ASoC probing. fsl_asoc_card_audmux_init() reads the zero-initialized priv->pdev before probe assigns it, then dev_err() dereferences the missing device pointer on an error path. Reachability requires the Freescale ASoC card driver, compatible audio hardware configuration, and an error that invokes diagnostic logging; the bounded impact is a kernel crash.
