CVE-2026-53041

A flaw was found in the Linux kernel's Oracle Cluster File System version 2 OCFS2. When an OCFS2 inode has both inline and and block-based extended attributes xattrs, the listxattr function can return a size larger than the caller's buffer. This incorrect size handling can lead to a kernel bug an...
