Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

netfilter: socket: Lookup orig tuple for IPv6 SNAT

nf_sk_lookup_slow_v4 does the conntrack lookup for IPv4 packets to restore the original 5-tuple in case of SNAT, to be able to find the right socket (if any). Then socket_match() can correctly check whether the socket was transparent.

However, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks this conntrack lookup, making xt_socket fail to match on the socket when the packet was SNATed. Add the same logic to nf_sk_lookup_slow_v6.

IPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, as pods' addresses are in the fd00::/8 ULA subnet and need to be replaced with the node's external address. Cilium leverages Envoy to enforce L7 policies, and Envoy uses transparent sockets. Cilium inserts an iptables prerouting rule that matches on `-m socket --transparent` and redirects the packets to localhost, but it fails to match SNATed IPv6 packets due to that missing conntrack lookup.

It was discovered that the CIFS network file system implementation in the Linux kernel did not properly verify the target namespace when handling upcalls. An attacker could use this to expose sensitive information. (CVE-2025-2312)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - PowerPC architecture; - x86 architecture; - iSCSI Boot Firmware Table Attributes driver; - GPU drivers; - HID subsystem; - InfiniBand drivers; - Media drivers; - MemoryStick subsystem; - Network drivers; - NTB driver; - PCI subsystem; - SCSI subsystem; - Thermal drivers; - JFS file system; - File systems infrastructure; - Tracing infrastructure; - 802.1Q VLAN protocol; - Asynchronous Transfer Mode (ATM) subsystem; - Bluetooth subsystem; - IPv6 networking; - Netfilter; - Network traffic control; - Sun RPC protocol; - USB sound devices; (CVE-2025-22007, CVE-2025-21959, CVE-2025-22021, CVE-2025-22063, CVE-2025-22045, CVE-2024-58093, CVE-2022-49636, CVE-2025-22020, CVE-2024-53168, CVE-2025-22071, CVE-2025-39735, CVE-2025-21991, CVE-2025-21992, CVE-2025-21996, CVE-2025-22035, CVE-2023-53034, CVE-2025-22054, CVE-2025-23136, CVE-2025-22073, CVE-2024-56551, CVE-2025-22005, CVE-2025-37937, CVE-2021-47211, CVE-2025-22086, CVE-2025-21956, CVE-2025-38637, CVE-2025-22004, CVE-2025-22018, CVE-2025-22079, CVE-2025-21957, CVE-2025-21993)
