What to do

AI-suggested

A fix for this resource leak has been implemented in the Linux kernel. Users should update to the fixed kernel version once available. No additional mitigation is required beyond applying the official patch.

Description

A resource leak vulnerability in the Linux kernel's blk_register_queue() function was fixed. The issue occurred when blk_mq_sysfs_register() succeeded but a subsequent error prevented proper cleanup, causing a memory leak due to missing blk_mq_sysfs_unregister() calls.
