DESCRIPTION
* CVE-2021-4155: Data leak in XFS filesystem.
The XFS filesystem does not correctly initialize certain data blocks. This
could allow data leaks to unprivileged users.
* CVE-2022-0185: Out-of-bounds memory access in the fsconfig system call.
An integer underflow in the fsconfig system calls could lead to an
out-of-bounds write access. A local unprivileged user could use this flaw
to elevate privileges.
