In the Linux kernel, the following vulnerability has been resolved:
bfq: Update cgroup information before merging bio
When the process is migrated to a different cgroup (or in case of writeback just starts submitting bios associated with a different cgroup) bfqmergebio() can operate with stale cgroup information in bic. Thus the bio can be merged to a request from a different cgroup or it can result in merging of bfqqs for different cgroups or bfqqs of already dead cgroups and causing possible use-after-free issues. Fix the problem by updating cgroup information in bfqmergebio().
