CVE-2025-40033: remoteproc: pru: Fix potential NULL pointer dereference in pru_rproc_set_ctable()

Published Oct 28, 2025
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

remoteproc: pru: Fix potential NULL pointer dereference in prurprocsetctable()

prurprocsetctable() accessed rproc->priv before the ISERRORNULL check, which could lead to a null pointer dereference. Move the pru assignment, ensuring we never dereference a NULL rproc pointer.
