CVE-2022-49343

Description

In the Linux kernel, the following vulnerability has been resolved:

ext4: avoid cycles in directory h-tree

A maliciously corrupted filesystem can contain cycles in the h-tree stored inside a directory. That can easily lead to the kernel corrupting tree nodes that were already verified under its hands while doing a node split and consequently accessing unallocated memory. Fix the problem by verifying traversed block numbers are unique.
