It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-49862 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-49862/ (Markdown: https://insights.sbomify.com/CVE-2022-49862/index.md)","id":"CVE-2022-49862","markdown":"https://insights.sbomify.com/CVE-2022-49862/index.md","name":"CVE-2022-49862","record":{"aliases":["DEBIAN-CVE-2022-49862","GHSA-qp6f-hq95-gpp9","UBUNTU-CVE-2022-49862"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger an uninitialized value read in the Linux kernel TIPC module, potentially disclosing sensitive kernel memory.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntipc: fix the msg-\u003ereq tlv len check in tipc_nl_compat_name_table_dump_header\n\nThis is a follow-up for commit 974cb0e3e7c9 (\"tipc: fix uninit-value\nin tipc_nl_compat_name_table_dump\") where it should have type casted\nsizeof(..) to int to work when TLV_GET_DATA_LEN() returns a negative\nvalue.\n\nsyzbot reported a call trace because of it:\n\n  BUG: KMSAN: uninit-value in ...\n   tipc_nl_compat_name_table_dump+0x841/0xea0 net/tipc/netlink_compat.c:934\n   __tipc_nl_compat_dumpit+0xab2/0x1320 net/tipc/netlink_compat.c:238\n   tipc_nl_compat_dumpit+0x991/0xb50 net/tipc/netlink_compat.c:321\n   tipc_nl_compat_recv+0xb6e/0x1640 net/tipc/netlink_compat.c:1324\n   genl_family_rcv_msg_doit net/netlink/genetlink.c:731 [inline]\n   genl_family_rcv_msg net/netlink/genetlink.c:775 [inline]\n   genl_rcv_msg+0x103f/0x1260 net/netlink/genetlink.c:792\n   netlink_rcv_skb+0x3a5/0x6c0 net/netlink/af_netlink.c:2501\n   genl_rcv+0x3c/0x50 net/netlink/genetlink.c:803\n   netlink_unicast_kernel net/netlink/af_netlink.c:1319 [inline]\n   netlink_unicast+0xf3b/0x1270 net/netlink/af_netlink.c:1345\n   netlink_sendmsg+0x1288/0x1440 net/netlink/af_netlink.c:1921\n   sock_sendmsg_nosec net/socket.c:714 [inline]\n   sock_sendmsg net/socket.c:734 [inline]","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"tipc: fix the msg-\u003ereq tlv len check in tipc_nl_compat_name_table_dump_header","id":"CVE-2022-49862","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"information_disclosure","year":"2022"},"n_packages":0,"n_references":8,"next":{"headline":"can: af_can: fix NULL pointer dereference in can_rx_register()","id":"CVE-2022-49863"},"packages":[],"prev":{"headline":"dmaengine: mv_xor_v2: Fix a resource leak in mv_xor_v2_remove()","id":"CVE-2022-49861"},"products":["Linux"],"published":"2025-05-01","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-23","vendors":["Linux"]},"summary":"A local attacker can trigger an uninitialized value read in the Linux kernel TIPC module, potentially disclosing sensitive kernel memory.","url":"https://insights.sbomify.com/CVE-2022-49862/"}
