An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53224 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-2026-53224/ (Markdown: https://insights.sbomify.com/CVE-2026-53224/index.md)","id":"CVE-2026-53224","markdown":"https://insights.sbomify.com/CVE-2026-53224/index.md","name":"CVE-2026-53224","record":{"aliases":["AZL-90522","BELL-CVE-2026-53224","DEBIAN-CVE-2026-53224","GHSA-h634-6f45-j5wj","ROOT-OS-DEBIAN-11-CVE-2026-53224","ROOT-OS-DEBIAN-12-CVE-2026-53224","ROOT-OS-DEBIAN-13-CVE-2026-53224","ROOT-OS-UBUNTU-2204-CVE-2026-53224","ROOT-OS-UBUNTU-2404-CVE-2026-53224","UBUNTU-CVE-2026-53224"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel SCTP","requires_auth":"none","summary":"A remote attacker can trigger out-of-bounds reads in the Linux kernel SCTP implementation by sending malformed COOKIE_ECHO chunks, potentially causing crashes or leaking memory.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: validate embedded INIT chunk and address list lengths in cookie\n\nsctp_unpack_cookie() only checked that the embedded INIT chunk length\ndid not exceed the remaining cookie payload, but did not ensure that the\nINIT chunk is large enough to contain a complete INIT header.\n\nA malformed COOKIE_ECHO can therefore carry a truncated INIT chunk whose\nlength field is smaller than sizeof(struct sctp_init_chunk).  Later,\nsctp_process_init() accesses INIT parameters unconditionally, which may\nlead to out-of-bounds reads.\n\nIn addition, raw_addr_list_len is not fully validated against the\nremaining cookie payload. When cookie authentication is disabled, an\nattacker can supply an oversized raw_addr_list_len and cause\nsctp_raw_to_bind_addrs() to read beyond the end of the cookie. The\naddress parser also lacks sufficient bounds checks for parameter headers\nand lengths, allowing malformed address parameters to trigger\nout-of-bounds reads.\n\nFix this by:\n\n- requiring the embedded INIT chunk length to be at least sizeof(struct\n  sctp_init_chunk);\n- validating that the INIT chunk and raw address list together fit\n  within the cookie payload;\n- verifying sufficient data exists for each address parameter header and\n  payload before parsing it.\n\nNote that sctp_verify_init() must be called after sctp_unpack_cookie()\nand before sctp_process_init() when cookie authentication is disabled.\nThis will be addressed in a separate patch.","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":"sctp: validate embedded INIT chunk and address list lengths in cookie","id":"CVE-2026-53224","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"sctp: fix uninit-value in __sctp_rcv_asconf_lookup()","id":"CVE-2026-53225"},"packages":[],"prev":{"headline":"net: guard timestamp cmsgs to real error queue skbs","id":"CVE-2026-53223"},"products":["Linux"],"published":"2026-06-25","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A remote attacker can trigger out-of-bounds reads in the Linux kernel SCTP implementation by sending malformed COOKIE_ECHO chunks, potentially causing crashes or leaking memory.","url":"https://insights.sbomify.com/CVE-2026-53224/"}
