## Overview

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

afs: Fix double-unmap of directory block

Fix afs_edit_dir_remove() to use a cleanup function to unmap the block
pointed to by afs_dir_iter::block if it's left pointing to something rather
than manually kunmapping the blocks.  Manually kunmapping without clearing
iter.blocks can result in a double-kunmap if afs_dir_find_block() is called
twice in a row (which would be the case if the block being modified is not
first in the hash chain).

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
