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-2026-89799 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-2026-89799/ (Markdown: https://insights.sbomify.com/CVE-2026-89799/index.md)","id":"CVE-2026-89799","markdown":"https://insights.sbomify.com/CVE-2026-89799/index.md","name":"CVE-2026-89799","record":{"aliases":["AZL-101343","BELL-CVE-2026-89799","DEBIAN-CVE-2026-89799","GHSA-p7rj-gh7c-64vc","UBUNTU-CVE-2026-89799"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"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 bpf_get_stackid function can lead to system instability or crashes due to improper preemption handling.","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\nbpf: Disable preemption in bpf_get_stackid\n\nThe get_perf_callchain call needs disabled preemption plus we need\nit disabled as long as we access its returned trace entries buffer.\n\nNote the bpf_get_stackid_pe function is executed already with\npreemption disabled.","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":"bpf: Disable preemption in bpf_get_stackid","id":"CVE-2026-89799","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"drm/nouveau/uvmm: clear the dirty flag when unwinding an OP_UNMAP_SPARSE","id":"CVE-2026-89800"},"packages":[],"prev":{"headline":"rpcrdma: arm rn_done before publishing the notification","id":"CVE-2026-89798"},"products":["Linux"],"published":"2026-09-16","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":"2026-10-21","vendors":["Linux"]},"summary":"A race condition in the Linux kernel's bpf_get_stackid function can lead to system instability or crashes due to improper preemption handling.","url":"https://insights.sbomify.com/CVE-2026-89799/"}
