Description SMASH SMASH 2024-05-20 15:29:53 UTC 
In the Linux kernel, the following vulnerability has been resolved:

block: fix module reference leakage from bdev_open_by_dev error path

At the time bdev_may_open() is called, module reference is grabbed
already, hence module reference should be released if bdev_may_open()
failed.

This problem is found by code review.
