CVE-2022-49531 Information

Description

In the Linux kernel the following vulnerability has been resolved:

loop: implement ->free_disk

Ensure that the lo_device which is stored in the gendisk private data is valid until the gendisk is freed. Currently the loop driver uses a lot of effort to make sure a device is not freed when it is still in use but to to fix a potential deadlock this will be relaxed a bit soon.
