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-2026-122192/ (Markdown: https://insights.sbomify.com/CVE-2026-122192/index.md)","id":"CVE-2026-122192","markdown":"https://insights.sbomify.com/CVE-2026-122192/index.md","name":"CVE-2026-122192","record":{"aliases":["GHSA-48ww-rqpp-2mgm"],"analysis":null,"analysis_generated_by":null,"assigner":"AMZN","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-825","name":"Expired Pointer Dereference"},{"id":"CWE-390","name":"Detection of Error Condition Without Action"}],"description":"Improper handling of a failed memory remap in Firecracker versions 0.23.0 through 1.16.1 might allow a guest user with root privileges to read or modify Firecracker VMM process memory via balloon or virtio-mem discard requests on microVMs restored from a snapshot with the File memory backend, if the host fails to create the replacement mapping.\n\nTo remediate this issue, users should upgrade to Firecracker 1.16.2 or 1.17.0 and later.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Guest access to Firecracker process memory after a failed memory discard","id":"CVE-2026-122192","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"OS command injection in the example SSM documents in Trusted Remote Execution (REX)","id":"CVE-2026-122193"},"nickname":null,"packages":[],"prev":{"headline":"itsourcecode Airline Reservation System manage_booked.php sql injection","id":"CVE-2026-122191"},"products":["firecracker"],"published":"2026-11-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2026-11-09","vendors":["AWS"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-122192/"}
