Описание
In the Linux kernel, the following vulnerability has been resolved:
fsi: occ: Prevent use after free
Use get_device and put_device in the open and close functions to
make sure the device doesn't get freed while a file descriptor is
open.
Also, lock around the freeing of the device buffer and check the
buffer before using it in the submit function.
A flaw was found in the Linux kernel's fsi:occ component. This use-after-free vulnerability occurs when a device is prematurely freed while a file descriptor is still open. A local attacker could exploit this condition to cause memory corruption, potentially leading to a denial of service or other unspecified impacts.
