In the Linux kernel before 5.1.6, there is a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service.
Reference and upstream commit:
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 1794400]
This was fixed for Fedora in the 5.1.6 stable kernel update.
To mitigate this issue, prevent module cpia2 from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
