CVE-2024-50137

Service interruption via NULL member access

Published Nov 5, 2024 · Updated May 11, 2026

NULL pointer dereference in the Linux JH7110 reset driver allows local users on affected kernels to interrupt service. The jh71x0_reset_status function XORs a reset-status value with data->asserted[offset] even though asserted is NULL on JH7110 systems, causing a kernel-mode page fault. Reaching the flaw requires local low-privileged access to request reset-control status on JH7110 hardware, and the reported consequence is limited to availability.
