Description
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.

Executive Summary

This vulnerability is a potential NULL pointer dereference in the Linux kernel's remoteproc subsystem, specifically in the pru_rproc_set_ctable() function. The function accessed a pointer (rproc->priv) before properly checking if the rproc pointer was NULL or an error, which could cause the system to dereference a NULL pointer and potentially crash or behave unexpectedly.

Impact Analysis

If exploited, this vulnerability could cause a system crash or instability due to a NULL pointer dereference in the Linux kernel, potentially leading to denial of service or unexpected behavior in systems using the affected remoteproc subsystem.
