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-2026-97522 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-97522/ (Markdown: https://insights.sbomify.com/CVE-2026-97522/index.md)","id":"CVE-2026-97522","markdown":"https://insights.sbomify.com/CVE-2026-97522/index.md","name":"CVE-2026-97522","record":{"aliases":["AZL-104567","BELL-CVE-2026-97522","DEBIAN-CVE-2026-97522","GHSA-pwwm-ccjp-fwfv","UBUNTU-CVE-2026-97522"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A bug in Linux kernel MPTCP accounting can cause byte counter mismatches, potentially leading to denial of service conditions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmptcp: fix bad accounting in __mptcp_subflow_push_pending()\n\nIf __subflow_push_pending() errors out we should avoid updating the\ncopied byte counters, to avoid mismatch push call later on.","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":"mptcp: fix bad accounting in __mptcp_subflow_push_pending()","id":"CVE-2026-97522","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"mptcp: close race between scheduler and state change","id":"CVE-2026-97523"},"packages":[],"prev":{"headline":"gfs2: fix quota init duplicate scan","id":"CVE-2026-97521"},"products":["Linux"],"published":"2026-09-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A bug in Linux kernel MPTCP accounting can cause byte counter mismatches, potentially leading to denial of service conditions.","url":"https://insights.sbomify.com/CVE-2026-97522/"}
