Description
In the Linux kernel, the following vulnerability has been resolved:
block: fix resource leak in blk_register_queue() error path
When registering a queue fails after blk_mq_sysfs_register() is
successful but the function later encounters an error, we need
to clean up the blk_mq_sysfs resources.
Add the missing blk_mq_sysfs_unregister() call in the error path
to properly clean up these resources and prevent a memory leak.
Affected configurations
• linux linux kernel (>= 3.13 < 6.6.88)
• linux linux kernel (>= 6.7 < 6.12.25)
• linux linux kernel (>= 6.13 < 6.14.4)
• linux linux kernel 6.15
