Vulnerability from github
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:
