CVE-2022-48710

Kernel crash via unchecked mode allocation failure

Published May 21, 2024 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel allows local users to crash the system through the Radeon native-mode display path. radeon_fp_native_mode() assigns the unchecked return from drm_mode_duplicate() to mode and dereferences it when allocation fails; the alternate drm_cvt_mode() path also lacked failure handling. Exploitation requires local low-privileged access and reachability of the Radeon mode-setting path, and the bounded consequence is a kernel crash.
