Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The vulnerability is related to the page pool get stats function in the mvneta driver. Calling this function without checks can lead to kernel crashes. The page pool is only available if the bm is not used, and it is not allocated when the port is stopped or in case of errors. This can cause a kernel NULL pointer dereference at virtual address 00000070, resulting in a crash. The issue is triggered when calling ethstats on a port that is down or at the wrong moment.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
