CVE-2026-43145

Local system crash via false resource table

Published May 6, 2026 · Updated May 6, 2026

Denial of service in the remoteproc driver in Linux Kernel allows local users to crash affected systems during firmware startup. The affected function returns priv->rsc_table when rproc->table_ptr is NULL, so the remoteproc core treats a nonexistent firmware resource table as loaded. Exploitation requires an rsc-table device-tree entry, firmware lacking a resource table, and local low-privilege access to initiate firmware loading.
