CVE-2022-50501

Kernel crash via unchecked CODA IRAM allocation

Published Oct 4, 2025 · Updated Oct 4, 2025

NULL pointer dereference in the CODA media driver in Linux allows local users to crash the kernel through video decoding activity. The coda_setup_iram routine continues IRAM buffer setup without immediately rejecting a zero return from coda_iram_alloc. Exploitation requires low-privileged local access, a reachable CODA device path, and an allocation failure; the documented consequence is availability loss only.
