Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-49017 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-2022-49017/ (Markdown: https://insights.sbomify.com/CVE-2022-49017/index.md)","id":"CVE-2022-49017","markdown":"https://insights.sbomify.com/CVE-2022-49017/index.md","name":"CVE-2022-49017","record":{"aliases":["DEBIAN-CVE-2022-49017","GHSA-m2gv-rr38-g5r4","UBUNTU-CVE-2022-49017"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel TIPC module allows attackers to cause a system crash via crafted network packets.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntipc: re-fetch skb cb after tipc_msg_validate\n\nAs the call trace shows, the original skb was freed in tipc_msg_validate(),\nand dereferencing the old skb cb would cause an use-after-free crash.\n\n  BUG: KASAN: use-after-free in tipc_crypto_rcv_complete+0x1835/0x2240 [tipc]\n  Call Trace:\n   \u003cIRQ\u003e\n   tipc_crypto_rcv_complete+0x1835/0x2240 [tipc]\n   tipc_crypto_rcv+0xd32/0x1ec0 [tipc]\n   tipc_rcv+0x744/0x1150 [tipc]\n  ...\n  Allocated by task 47078:\n   kmem_cache_alloc_node+0x158/0x4d0\n   __alloc_skb+0x1c1/0x270\n   tipc_buf_acquire+0x1e/0xe0 [tipc]\n   tipc_msg_create+0x33/0x1c0 [tipc]\n   tipc_link_build_proto_msg+0x38a/0x2100 [tipc]\n   tipc_link_timeout+0x8b8/0xef0 [tipc]\n   tipc_node_timeout+0x2a1/0x960 [tipc]\n   call_timer_fn+0x2d/0x1c0\n  ...\n  Freed by task 47078:\n   tipc_msg_validate+0x7b/0x440 [tipc]\n   tipc_crypto_rcv_complete+0x4b5/0x2240 [tipc]\n   tipc_crypto_rcv+0xd32/0x1ec0 [tipc]\n   tipc_rcv+0x744/0x1150 [tipc]\n\nThis patch fixes it by re-fetching the skb cb from the new allocated skb\nafter calling tipc_msg_validate().","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: re-fetch skb cb after tipc_msg_validate","id":"CVE-2022-49017","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":4,"next":{"headline":"mptcp: fix sleep in atomic at close time","id":"CVE-2022-49018"},"packages":[],"prev":{"headline":"net: mdiobus: fix unbalanced node reference count","id":"CVE-2022-49016"},"products":["Linux"],"published":"2024-10-21","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":"2026-08-05","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel TIPC module allows attackers to cause a system crash via crafted network packets.","url":"https://insights.sbomify.com/CVE-2022-49017/"}
