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-2026-74306 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-2026-74306/ (Markdown: https://insights.sbomify.com/CVE-2026-74306/index.md)","id":"CVE-2026-74306","markdown":"https://insights.sbomify.com/CVE-2026-74306/index.md","name":"CVE-2026-74306","record":{"aliases":["BELL-CVE-2026-74306","DEBIAN-CVE-2026-74306","GHSA-5q42-qm7h-h2q2","UBUNTU-CVE-2026-74306"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel's vfio/qat driver allows concurrent writers to bypass bounds checks, potentially leading to memory corruption and privilege escalation.","user_interaction":"not_required","vuln_class":"race_condition"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nvfio/qat: fix f_pos race in qat_vf_resume_write()\n\nqat_vf_resume_write() checks filp-\u003ef_pos before taking migf-\u003elock, but\ncopies into the migration-state buffer after taking the lock and\nre-reading the shared file position.\n\nTwo concurrent writers could therefore pass the bounds check with the\nold offset, then have the second writer copy after the first advanced\nf_pos, writing past the end of the migration-state buffer.\n\nTake migf-\u003elock before doing the boundary checks.","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":"vfio/qat: fix f_pos race in qat_vf_resume_write()","id":"CVE-2026-74306","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"ext4: validate donor file superblock early in EXT4_IOC_MOVE_EXT","id":"CVE-2026-74307"},"packages":[],"prev":{"headline":"bpf: Tighten cgroup storage cookie checks for prog arrays","id":"CVE-2026-74305"},"products":["Linux"],"published":"2026-08-15","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":"2026-08-17","vendors":["Linux"]},"summary":"A race condition in the Linux kernel's vfio/qat driver allows concurrent writers to bypass bounds checks, potentially leading to memory corruption and privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-74306/"}
