Technical description

In the Linux kernel, the following vulnerability has been resolved:

scsi: mpi3mr: Add NULL checks when resetting request and reply queues

The driver encountered a crash during resource cleanup when the reply and

request queues were NULL due to freed memory. This issue occurred when the

creation of reply or request queues failed, and the driver freed the memory

first, but attempted to mem set the content of the freed memory, leading to

a system crash.

Add NULL pointer checks for reply and request queues before accessing the

reply/request memory during cleanup

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
