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-2026-68383 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-2026-68383/ (Markdown: https://insights.sbomify.com/CVE-2026-68383/index.md)","id":"CVE-2026-68383","markdown":"https://insights.sbomify.com/CVE-2026-68383/index.md","name":"CVE-2026-68383","record":{"aliases":["BELL-CVE-2026-68383","DEBIAN-CVE-2026-68383","GHSA-hf5h-j5wg-pf5g","UBUNTU-CVE-2026-68383"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's Xe GPU driver allows attackers to potentially execute code or cause a system crash.","user_interaction":"not_required","vuln_class":"use_after_free"},"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-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/guc: Keep scheduler timeline name alive\n\nThe scheduler keeps a pointer to the timeline name, but q-\u003ename\nis freed with the exec queue while scheduler fences can still\nreference it.\n\nStore the name in struct xe_guc_exec_queue so it shares\nthe scheduler's RCU-deferred lifetime.\n\n(cherry picked from commit 41075f0eb5dcbd3b065d15f15ef7bbe9315188e8)","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/xe/guc: Keep scheduler timeline name alive","id":"CVE-2026-68383","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"drm/xe/vf: Fix VF CCS attach/detach race with in-flight BO moves","id":"CVE-2026-68384"},"packages":[],"prev":{"headline":"drm/xe/guc: Hold device ref until queue teardown completes","id":"CVE-2026-68382"},"products":["Linux"],"published":"2026-08-10","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":"2026-10-21","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's Xe GPU driver allows attackers to potentially execute code or cause a system crash.","url":"https://insights.sbomify.com/CVE-2026-68383/"}
