CVE-2026-53309

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An off-by-one error exists in the dlm match regions() function within the ocfs2/dlm component. The local-vs-remote region comparison loop incorrectly uses the <= operator instead of <, which leads to an out-of-bounds read of one entry beyond the valid range of qr regions.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
