Description OSIDB Bzimport 2025-10-28 12:04:23 UTC 
In the Linux kernel, the following vulnerability has been resolved:

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

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