27 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Fix possible crash when setting up bsg fails If bsg_setup_queue() fails, the bsg_queue is assigned a non-NULL value. Consequently, in mpi3mr_bsg_exit(), the condition "if(!mrioc->bsg_queue)" will not be satisfied, preventing execution from entering bsg_remove_queue(), which could lead to the following crash: BUG: kernel NULL pointer dereference, address: 000000000000041c Call Trace:
