CVE-2026-31706
In ksmbd (Linux kernel), CVE-2026-31706 is due to a validation flaw in smb_inherit_dacl(): the on-disk num_aces from a parent directory’s security.NTACL is trusted to size a heap allocation (kmalloc(sizeof(struct smb_ace) * num_aces * 2)) without verifying consistency with pdacl_size. An authenti...
