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-2026-93520/ (Markdown: https://insights.sbomify.com/CVE-2026-93520/index.md)","id":"CVE-2026-93520","markdown":"https://insights.sbomify.com/CVE-2026-93520/index.md","name":"CVE-2026-93520","record":{"aliases":["AZL-111455","AZL-111491","BELL-CVE-2026-93520","DEBIAN-CVE-2026-93520","ECHO-200f-d15d-9fa0","GHSA-wgf4-w3hh-3mvm","UBUNTU-CVE-2026-93520"],"analysis":null,"analysis_generated_by":null,"assigner":"suse","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A heap buffer overflow caused by mismatching size calculations between XkbAllocNames and  ChangeKeycodeRange in X.org X server before 2.1.25 and XWayland before 24.1.14 could be used by authenticated X clients to crash or potentially execute code in X server context.","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":"X.Org Server XKB ChangeKeycodeRange Heap Out-of-Bounds Write","id":"CVE-2026-93520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"X.Org Server RandR ChangeProviderProperty Heap Buffer Overflow","id":"CVE-2026-93521"},"packages":[],"prev":{"headline":"X.Org Server XFixes Pointer Barrier Event List Buffer Overflow","id":"CVE-2026-93519"},"products":["xorg-x11-server","xwayland"],"published":"2026-10-28","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-28","vendors":["x.org"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-93520/"}
