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-2026-98041 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-2026-98041/ (Markdown: https://insights.sbomify.com/CVE-2026-98041/index.md)","id":"CVE-2026-98041","markdown":"https://insights.sbomify.com/CVE-2026-98041/index.md","name":"CVE-2026-98041","record":{"aliases":["AZL-104495","BELL-CVE-2026-98041","DEBIAN-CVE-2026-98041","GHSA-2hhx-gj64-2962","UBUNTU-CVE-2026-98041"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel BPF","requires_auth":"low_privilege","summary":"A logic error in the Linux kernel BPF verifier allows bypassing safety checks, potentially enabling arbitrary code execution.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/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: Don't predict JMP32 pointer vs zero comparisons\n\nConsider the following program:\n\n        r1 = map_value;      /* low 32 bits are zero at runtime */\n        r6 = 0xdead000000000000;\n        if w1 != 0 goto l1;\n    l0: r1 += r6;\n        r2 = *(u64 *)(r1 + 0);\n        exit;\n    l1: r6 = 0;\n        goto l0;\n\nAt the moment is_branch_taken() reports the jump as always taken,\nbecause it does not distinguish between BPF_JMP and BPF_JMP32\ncomparisons when processing 'if w1 != 0 ...'.","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: Don't predict JMP32 pointer vs zero comparisons","id":"CVE-2026-98041","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"bpf: Don't resurrect a scalar id dropped by collect_linked_regs()","id":"CVE-2026-98042"},"packages":[],"prev":{"headline":"bpf: Mark the zero register precise for a register-form NULL check","id":"CVE-2026-98040"},"products":["Linux"],"published":"2026-09-25","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 logic error in the Linux kernel BPF verifier allows bypassing safety checks, potentially enabling arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2026-98041/"}
