"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: act_mpls: Fix warning during failed attribute validation\n\nThe 'TCA_MPLS_LABEL' attribute is of 'NLA_U32' type, but has a\nvalidation type of 'NLA_VALIDATE_FUNCTION'. This is an invalid\ncombination according to the comment above 'struct nla_policy':\n\n\"\nMeaning of `validate' field, use via NLA_POLICY_VALIDATE_FN:\n NLA_BINARY Validation function called for the attribute.\n All other Unused - but note that it's a union\n\"\n\nThis can trigger the warning [1] in nla_get_range_unsigned() when\nvalidation of the attribute fails. Despite being of 'NLA_U32' type, the\nassociated 'min'/'max' fields in the policy are negative as they are\naliased by the 'validate' field.\n\nFix by changing the attribute type to 'NLA_BINARY' which is consistent\nwith the above comment and all other users of NLA_POLICY_VALIDATE_FN().\nAs a result, move the length validation to the validation function.\n\nNo regressions in MPLS tests:\n\n # ./tdc.py -f tc-tests/actions/mpls.json\n [...]\n # echo $?\n 0\n\n[1]\nWARNING: CPU: 0 PID: 17743 at lib/nlattr.c:118\nnla_get_range_unsigned+0x1d8/0x1e0 lib/nlattr.c:117\nModules linked in:\nCPU: 0 PID: 17743 Comm: syz-executor.0 Not tainted 6.1.0-rc8 #3\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS\nrel-1.13.0-48-gd9c812dda519-prebuilt.qemu.org 04/01/2014\nRIP: 0010:nla_get_range_unsigned+0x1d8/0x1e0 lib/nlattr.c:117\n[...]\nCall Trace:\n <TASK>\n __netlink_policy_dump_write_attr+0x23d/0x990 net/netlink/policy.c:310\n netlink_policy_dump_write_attr+0x22/0x30 net/netlink/policy.c:411\n netlink_ack_tlv_fill net/netlink/af_netlink.c:2454 [inline]\n netlink_ack+0x546/0x760 net/netlink/af_netlink.c:2506\n netlink_rcv_skb+0x1b7/0x240 net/netlink/af_netlink.c:2546\n rtnetlink_rcv+0x18/0x20 net/core/rtnetlink.c:6109\n netlink_unicast_kernel net/netlink/af_netlink.c:1319 [inline]\n netlink_unicast+0x5e9/0x6b0 net/netlink/af_netlink.c:1345\n netlink_sendmsg+0x739/0x860 net/netlink/af_netlink.c:1921\n sock_sendmsg_nosec net/socket.c:714 [inline]\n sock_sendmsg net/socket.c:734 [inline]\n ____sys_sendmsg+0x38f/0x500 net/socket.c:2482\n ___sys_sendmsg net/socket.c:2536 [inline]\n __sys_sendmsg+0x197/0x230 net/socket.c:2565\n __do_sys_sendmsg net/socket.c:2574 [inline]\n __se_sys_sendmsg net/socket.c:2572 [inline]\n __x64_sys_sendmsg+0x42/0x50 net/socket.c:2572\n do_syscall_x64 arch/x86/entry/common.c:50 [inline]\n do_syscall_64+0x2b/0x70 arch/x86/entry/common.c:80\n entry_SYSCALL_64_after_hwframe+0x63/0xcd"
