Description
In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix reflink preserve cleanup issue commit c06c303832ec ("ocfs2: fix xattr array entry __counted_by error") doesn't handle all cases and the cleanup job for preserved xattr entries still has bug: - the 'last' pointer should be shifted by one unit after cleanup an array entry. - current code logic doesn't cleanup the first entry when xh_count is 1. Note, commit c06c303832ec is also a bug fix for 0fe9b66c65f3.
