AI-suggested
A fix for this vulnerability is available in Linux kernel version 6.1. Users and administrators should update to this version or later to remediate the issue. No additional mitigation steps are required beyond applying the official patch.
Description
A NULL pointer dereference vulnerability in the Linux kernel's mpi3mr driver was fixed. The issue occurs because sas_port_alloc_num() can return NULL on memory allocation failure, but this return value was not checked before being passed to sas_port_add(), leading to a potential NULL pointer dereference. Additionally, failure to free allocated memory on sas_port_add() failure could cause a memory leak. This vulnerability affects Linux kernel version 6.1.
