CVE-2025-38152

Kernel crash via stale remoteproc resource-table size

Published Apr 18, 2025 · Updated May 11, 2026

NULL pointer dereference in Linux remoteproc allows local users to crash the kernel through a crafted firmware restart sequence. rproc_shutdown clears cached_table but leaves table_sz nonzero, so rproc_start passes a NULL source and stale length to memcpy when replacement firmware lacks a resource table. Triggering the fault requires an i.MX8MP or i.MX9 system, an initial U-Boot-started remote processor with a fixed-address table, and sufficient privilege to stop it, load firmware, and restart it.
