This field corresponds to the sdiag_raw_protocol\nfield in struct inet_diag_req_raw.\ninet_diag_get_exact_compat() converts inet_diag_req to\ninet_diag_req_v2, but leaves the pad field uninitialized. So the issue\noccurs when raw_lookup() accesses the sdiag_raw_protocol field.\nFix this by initializing the pad field in\ninet_diag_get_exact_compat(). Also, do the same fix in\ninet_diag_dump_compat() to avoid the similar issue in the future.\n[1]\nBUG: KMSAN: uninit-value in raw_lookup net/ipv4/raw_diag.c:49 [inline]\nBUG: KMSAN: uninit-value in raw_sock_get+0x657/0x800 net/ipv4/raw_diag.c:71\nraw_lookup net/ipv4/raw_diag.c:49 [inline]\nraw_sock_get+0x657/0x800 net/ipv4/raw_diag.c:71\nraw_diag_dump_one+0xa1/0x660 net/ipv4/raw_diag.c:99\ninet_diag_cmd_exact+0x7d9/0x980\ninet_diag_get_exact_compat net/ipv4/inet_diag.c:1404 [inline]\ninet_diag_rcv_msg_compat+0x469/0x530 net/ipv4/inet_diag.c:1426\nsock_diag_rcv_msg+0x23d/0x740 net/core/sock_diag.c:282\nnetlink_rcv_skb+0x537/0x670 net/netlink/af_netlink.c:2564\nsock_diag_rcv+0x35/0x40 net/core/sock_diag.c:297\nnetlink_unicast_kernel net/netlink/af_netlink.c:1335 [inline]\nnetlink_unicast+0xe74/0x1240 net/netlink/af_netlink.c:1361\nnetlink_sendmsg+0x10c6/0x1260 net/netlink/af_netlink.c:1905\nsock_sendmsg_nosec net/socket.c:730 [inline]\n__sock_sendmsg+0x332/0x3d0 net/socket.c:745\n____sys_sendmsg+0x7f0/0xb70 net/socket.c:2585\n___sys_sendmsg+0x271/0x3b0 net/socket.c:2639\n__sys_sendmsg net/socket.c:2668 [inline]\n__do_sys_sendmsg net/socket.c:2677 [inline]\n__se_sys_sendmsg net/socket.c:2675 [inline]\n__x64_sys_sendmsg+0x27e/0x4a0 net/socket.c:2675\nx64_sys_call+0x135e/0x3ce0 arch/x86/include/generated/asm/syscalls_64.h:47\ndo_syscall_x64 arch/x86/entry/common.c:52 [inline]\ndo_syscall_64+0xd9/0x1e0 arch/x86/entry/common.c:83\nentry_SYSCALL_64_after_hwframe+0x77/0x7f\nUninit was stored to memory at:\nraw_sock_get+0x650/0x800 net/ipv4/raw_diag.c:71\nraw_diag_dump_one+0xa1/0x660 net/ipv4/raw_diag.c:99\ninet_diag_cmd_exact+0x7d9/0x980\ninet_diag_get_exact_compat net/ipv4/inet_diag.c:1404 [inline]\ninet_diag_rcv_msg_compat+0x469/0x530 net/ipv4/inet_diag.c:1426\nsock_diag_rcv_msg+0x23d/0x740 net/core/sock_diag.c:282\nnetlink_rcv_skb+0x537/0x670 net/netlink/af_netlink.c:2564\nsock_diag_rcv+0x35/0x40 net/core/sock_diag.c:297\nnetlink_unicast_kernel net/netlink/af_netlink.c:1335 [inline]\nnetlink_unicast+0xe74/0x1240 net/netlink/af_netlink.c:1361\nnetlink_sendmsg+0x10c6/0x1260 net/netlink/af_netlink.c:1905\nsock_sendmsg_nosec net/socket.c:730 [inline]\n__sock_sendmsg+0x332/0x3d0 net/socket.c:745\n____sys_sendmsg+0x7f0/0xb70 net/socket.c:2585\n___sys_sendmsg+0x271/0x3b0 net/socket.c:2639\n__sys_sendmsg net/socket.c:2668 [inline]\n__do_sys_sendmsg net/socket.c:2677 [inline]\n__se_sys_sendmsg net/socket.c:2675 [inline]\n__x64_sys_sendmsg+0x27e/0x4a0 net/socket.c:2675\nx64_sys_call+0x135e/0x3ce0 arch/x86/include/generated/asm/syscalls_64.h:47\ndo_syscall_x64 arch/x86/entry/common.c:52 [inline]\ndo_syscall_64+0xd9/0x1e0 arch/x86/entry/common.c:83\nentry_SYSCALL_64_after_hwframe+0x77/0x7f\nLocal variable req.i created at:\ninet_diag_get_exact_compat net/ipv4/inet_diag.c:1396 [inline]\ninet_diag_rcv_msg_compat+0x2a6/0x530 net/ipv4/inet_diag.c:1426\nsock_diag_rcv_msg+0x23d/0x740 net/core/sock_diag.c:282\nCPU: 1 PID: 8888 Comm: syz-executor.6 Not tainted 6.10.0-rc4-00217-g35bb670d65fc #32\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-2.fc40 04/01/2014"], "mitigation": {"lang": "en:us", "value": "Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability."}, "name": "CVE-2024-42106", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Out of support scope", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Out of support scope", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Out of support scope", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Will not fix", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Will not fix", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Will not fix", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Will not fix", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2024-07-30T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2024-42106\nhttps://nvd.nist.gov/vuln/detail/CVE-2024-42106\nhttps://lore.kernel.org/linux-cve-announce/2024073020-CVE-2024-42106-a042@gregkh/T"], "threat_severity": "Moderate", "upstream_fix": "kernel 4.19.318, kernel 5.4.280, kernel 5.10.222, kernel 5.15.163, kernel 6.1.98, kernel 6.6.39, kernel 6.9.9, kernel 6.10"}
