Description OSIDB Bzimport 2025-02-26 03:04:12 UTC 
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.
