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-2026-80836 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-2026-80836/ (Markdown: https://insights.sbomify.com/CVE-2026-80836/index.md)","id":"CVE-2026-80836","markdown":"https://insights.sbomify.com/CVE-2026-80836/index.md","name":"CVE-2026-80836","record":{"aliases":["AZL-99546","BELL-CVE-2026-80836","DEBIAN-CVE-2026-80836","GHSA-4c27-p37x-4j2h","UBUNTU-CVE-2026-80836"],"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":"none","summary":"A malicious virtio backend can trigger an out-of-bounds read in the Linux kernel crypto subsystem, leaking adjacent kernel heap memory to the caller.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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\ncrypto: virtio - bound the akcipher result length\n\nvirtio_crypto_dataq_akcipher_callback() sets the result length from the\ndevice-reported response length without bounding it to the destination\nbuffer, which was allocated for the original request length.\nsg_copy_from_buffer() then reads that many bytes from the destination\nbuffer; a backend reporting a larger length over-reads adjacent kernel\nheap into the caller's scatterlist (an out-of-bounds read).\n\nClamp the reported length to the originally requested destination length.\nA conforming device reports no more than that, so valid results are\nunaffected.","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":"crypto: virtio - bound the akcipher result length","id":"CVE-2026-80836","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"netfilter: nf_tables: don't queue packet path object notifications","id":"CVE-2026-80837"},"packages":[],"prev":{"headline":"crypto: qcom-rng - Remove crypto_rng interface","id":"CVE-2026-80835"},"products":["Linux"],"published":"2026-09-04","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 malicious virtio backend can trigger an out-of-bounds read in the Linux kernel crypto subsystem, leaking adjacent kernel heap memory to the caller.","url":"https://insights.sbomify.com/CVE-2026-80836/"}
