Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.6.111/6.12.52/6.17.2. This issue affects the function pru_rproc_set_ctable of the component remoteproc. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

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.
