CVE-2023-54107 blk-cgroup: dropping parent refcount after pd_free_fn() is done

In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: dropping parent refcount after pdfreefn is done Some cgroup policies will access parent pd through child pd even after pdofflinefn is done. If pdfreefn for parent is called before child, then UAF can be triggered. Hen...

CVE-2023-54107

CVE-2023-54107 relates to the Linux kernel blk-cgroup Use-After-Free caused by the parent blkg refcount being dropped before the parent’s pd_free_fn() executes. The issue occurs because __blkg_release() drops the parent refcount in a path that precedes the asynchronous blkg_free_work_fn() where p...
