CVE-2026-64401
CVE-2026-64401 affects the Linux kernel SMB/CIFS client. The bug occurs in cifs_swn_notify() which, under cifs_swnreg_idr_mutex, uses a cached tcon pointer that is not a stable reference, risking use-after-free when multiple tcons exist for a net/share. A same-share mount can keep the registratio...
