CVE-2025-37954

CVE-2025-37954 affects the Linux kernel SMB client logic. The issue is a race in open_cached_dir with lease breaks where a pre-existing valid cfid returned by find_or_create_cached_dir can race with a queued lease break, causing open_cached_dir to treat it as newly constructed and leak a dentry r...
