Описание
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, aka CID-dea37a972655.
A use-after-free flaw was found in the Linux kernel module, cpia2, in how it handled camera connections. This flaw allows an attacker with physical access to crash the system.
Меры по смягчению последствий
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.
