In the Linux kernel, the following vulnerability has been resolved:
udf: Detect system inodes linked into directory hierarchy
When UDF filesystem is corrupted, hidden system inodes can be linked into directory hierarchy which is an avenue for further serious corruption of the filesystem and kernel confusion as noticed by syzbot fuzzed images. Refuse to access system inodes linked into directory hierarchy and vice versa.
