CVE-2021-45868
This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file.
MEDIUM 5.5EPSS 1.34%
Does this matter?
Lower severity and a low EPSS score (1.34%). Track it; it rarely justifies an emergency change on its own.
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.
