Description

CVE-2022-49531 affecting package kernel 5.15.200.1-1

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

still in use, but to to fix a potential deadlock this will be relaxed

a bit soon.
