The vulnerability of the blkcg_deactivate_policy() function in the block/blk-cgroup.c module, which supports the block-level kernel in the Linux operating system, allows a malicious actor to trigger a service failure.

The vulnerability of the blkcgdeactivatepolicy function in the block/blk-cgroup.c module, which supports the block-level kernel in Linux, relates to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker to cause service failures...
