Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bloquear: reparar la fuga de referencia del módulo de la ruta de error bdev_open_by_dev. En el momento en que se llama a bdev_may_open(), la referencia del módulo ya está tomada, por lo tanto, la referencia del módulo debe liberarse si bdev_may_open() fallo. Este problema se encuentra mediante la revisión del código.
