CVE-2021-45868: Use After Free

First published: Fri Mar 18 2022(Updated: )

In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file.
