CVE-2025-40320

CVE-2025-40320 stems from a use-after-free in the Linux kernel SMB client path. Specifically, in smb2_query_info_compound(), when the operation is retried, a previously allocated cfid could be freed on the first attempt and, because cfid isn’t reset on replay, a later cleanup may act on a stale p...
