Description
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.
A use-after-free vulnerability was found in the Linux kernel. The quota mechanism doesn't properly validate the quota block number, triggering a use-after-free bug in the RWSem code, leading to a denial of service.
