CVE-2026-23310

Summary: CVE-2026-23310 affects the Linux kernel bonding/kern XDP path. If a bond is in 802.3ad or balance-xor mode and an XDP program is loaded, changing xmit_hash_policy to vlan+srcmac can escape the existing guard, leaving bond->xdp_prog set and causing an incompatible state during tear-dow...
