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-2026-68446 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-2026-68446/ (Markdown: https://insights.sbomify.com/CVE-2026-68446/index.md)","id":"CVE-2026-68446","markdown":"https://insights.sbomify.com/CVE-2026-68446/index.md","name":"CVE-2026-68446","record":{"aliases":["BELL-CVE-2026-68446","DEBIAN-CVE-2026-68446","GHSA-55wx-2w5g-rcrg","UBUNTU-CVE-2026-68446"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A missing validation of user-supplied array size in the vmwgfx driver can lead to memory corruption, potentially causing denial of service or code execution.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","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-20","name":"Improper Input Validation"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/vmwgfx: Validate vmw_surface_metadata::array_size\n\nThis field comes from userspace and should be validated against specific\nlimits depending on which Shader Model (SM) is available.","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":"drm/vmwgfx: Validate vmw_surface_metadata::array_size","id":"CVE-2026-68446","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"drm/amdkfd: clamp v9 CRIU control stack checkpoint copy to BO size","id":"CVE-2026-68447"},"packages":[],"prev":{"headline":"drm/vc4: Prevent shader BO mappings from becoming writable","id":"CVE-2026-68445"},"products":["Linux"],"published":"2026-08-12","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":"2026-10-19","vendors":["Linux"]},"summary":"A missing validation of user-supplied array size in the vmwgfx driver can lead to memory corruption, potentially causing denial of service or code execution.","url":"https://insights.sbomify.com/CVE-2026-68446/"}
