Race condition In linux

Description

A flaw was found in the Linux kernel's block cgroup (blk-cgroup) component. A local attacker could exploit a race condition in the blkcg_activate_policy() function, where block group policy data (blkg_policy_data) is installed before it is fully initialized. This allows another function, ioc_weight_write(), to access uninitialized data, leading to a NULL pointer dereference and causing a system crash, resulting in a Denial of Service (DoS).

Mitigation
