CVE-2026-64146

The CVE-2026-64146 issue affects the Linux kernel’s EROFS subsystem, specifically an inode xattrs metabuf leak in the xattr initialization path. The root cause was improper cleanup after erofs_read_metabuf(), where a metabuf could leak a folio reference via out_unlock paths. The fix consolidates ...
