NVD

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.
