CVE-2026-53309

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

ocfs2/dlm: fix off-by-one in dlm_match_regions() region comparison

The local-vs-remote region comparison loop uses '<=' instead of '<',
causing it to read one entry past the valid range of qr_regions.  The
other loops in the same function correctly use '<'.

Fix the loop condition to use '<' for consistency and correctness.
