A memory out-of-bounds read flaw was found in the Linux kernel before
5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory
with broken indexing. This flaw allows a local user to crash the system if
the directory exists. The highest threat from this vulnerability is to
system availability.
