      "title": "bpf: Reject dev-bound-only programs on other devices",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject dev-bound-only programs on other devices\n\n__bpf_offload_dev_match() falls back to comparing offdev pointers after an\nexact netdev mismatch. Bound-only programs normally have NULL offdevs, so\nunrelated netdevs compare equal. A bound-only program on an\noffload-registered netdev can instead inherit a real offdev and match a\nsibling port. With CAP_BPF and CAP_NET_ADMIN, a caller can use\nbpf(BPF_LINK_CREATE) with a different target ifindex to run metadata kfuncs\nspecialized for the bound driver on the target driver's xdp_buff. Running a\nveth-bound program on tun reads beyond tun's bare stack xdp_buff as a\nveth_xdp_buff.\n\n  Oops: general protection fault, probably for non-canonical address\n  KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017]\n  RIP: 0010:veth_xdp_rx_timestamp (drivers/net/veth.c:1673)\n  Call Trace:\n   ...\n   tun_build_skb (drivers/net/tun.c:1739)\n   tun_get_user (drivers/net/tun.c:1856)\n   tun_chr_write_iter (drivers/net/tun.c:2091)\n   vfs_write (fs/read_write.c:595 fs/read_write.c:687)\n   ksys_write (fs/read_write.c:739)\n   do_syscall_64 (arch/x86/entry/syscall_64.c:84)\n   entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:121)\n  Kernel panic - not syncing: Fatal exception in interrupt\n\nRestrict non-offloaded programs to exact netdev matches and retain the\nshared-offdev fallback only for genuinely offloaded multi-port programs.",
