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-2026-53225 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-2026-53225/ (Markdown: https://insights.sbomify.com/CVE-2026-53225/index.md)","id":"CVE-2026-53225","markdown":"https://insights.sbomify.com/CVE-2026-53225/index.md","name":"CVE-2026-53225","record":{"aliases":["AZL-90732","BELL-CVE-2026-53225","DEBIAN-CVE-2026-53225","GHSA-fj73-9fr6-g7mw","ROOT-OS-DEBIAN-11-CVE-2026-53225","ROOT-OS-DEBIAN-12-CVE-2026-53225","ROOT-OS-UBUNTU-2204-CVE-2026-53225","ROOT-OS-UBUNTU-2404-CVE-2026-53225","UBUNTU-CVE-2026-53225"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SCTP","requires_auth":"none","summary":"An unauthenticated SCTP peer can trigger a read of uninitialized memory in the Linux kernel, potentially disclosing sensitive data.","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":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-908","name":"Use of Uninitialized Resource"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: fix uninit-value in __sctp_rcv_asconf_lookup()\n\n__sctp_rcv_asconf_lookup() in net/sctp/input.c only checks that the ASCONF\nchunk can hold the ADDIP header and a parameter header, then calls\naf-\u003efrom_addr_param(), which reads the full address (16 bytes for IPv6)\ntrusting the parameter's declared length.\n\nAn unauthenticated peer can send a truncated trailing ASCONF chunk that\ndeclares an IPv6 address parameter but stops after the 4-byte parameter\nheader; reached from the no-association lookup path, from_addr_param() then\nreads uninitialized bytes past the parameter.\n\nImpact: an unauthenticated SCTP peer makes the receive path read up to 16\nbytes of uninitialized memory past a truncated ASCONF address parameter.\n\nThe sibling __sctp_rcv_init_lookup() bounds parameters with\nsctp_walk_params(); this path open-codes the fetch and omits the bound.\nVerify the whole address parameter lies within the chunk before\nfrom_addr_param() reads it, the same class of fix as commit 51e5ad549c43\n(\"net: sctp: fix KMSAN uninit-value in sctp_inq_pop\").","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: fix uninit-value in __sctp_rcv_asconf_lookup()","id":"CVE-2026-53225","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"gpio: rockchip: fix generic IRQ chip leak on remove","id":"CVE-2026-53226"},"packages":[],"prev":{"headline":"sctp: validate embedded INIT chunk and address list lengths in cookie","id":"CVE-2026-53224"},"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":"2026-10-19","vendors":["Linux"]},"summary":"An unauthenticated SCTP peer can trigger a read of uninitialized memory in the Linux kernel, potentially disclosing sensitive data.","url":"https://insights.sbomify.com/CVE-2026-53225/"}
