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-2025-68314 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-2025-68314/ (Markdown: https://insights.sbomify.com/CVE-2025-68314/index.md)","id":"CVE-2025-68314","markdown":"https://insights.sbomify.com/CVE-2025-68314/index.md","name":"CVE-2025-68314","record":{"aliases":["BELL-CVE-2025-68314","DEBIAN-CVE-2025-68314","GHSA-3c4x-fc2p-3977","UBUNTU-CVE-2025-68314"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel DRM","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's DRM MSM driver allows attackers to cause a system crash by triggering faults during context closure.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/msm: make sure last_fence is always updated\n\nUpdate last_fence in the vm-bind path instead of kernel managed path.\n\nlast_fence is used to wait for work to finish in vm_bind contexts but not\nused for kernel managed contexts.\n\nThis fixes a bug where last_fence is not waited on context close leading\nto faults as resources are freed while in use.\n\nPatchwork: https://patchwork.freedesktop.org/patch/680080/","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/msm: make sure last_fence is always updated","id":"CVE-2025-68314","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"f2fs: fix to detect potential corrupted nid in free_nid_list","id":"CVE-2025-68315"},"packages":[],"prev":{"headline":"x86/CPU/AMD: Add RDSEED fix for Zen5","id":"CVE-2025-68313"},"products":["Linux"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's DRM MSM driver allows attackers to cause a system crash by triggering faults during context closure.","url":"https://insights.sbomify.com/CVE-2025-68314/"}
