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-2025-40050 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-2025-40050/ (Markdown: https://insights.sbomify.com/CVE-2025-40050/index.md)","id":"CVE-2025-40050","markdown":"https://insights.sbomify.com/CVE-2025-40050/index.md","name":"CVE-2025-40050","record":{"aliases":["BELL-CVE-2025-40050","GHSA-p3rp-6995-mvj3","UBUNTU-CVE-2025-40050"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel BPF verifier allows incorrect scalar adjustments for pointer registers, potentially enabling privilege escalation or code execution.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Skip scalar adjustment for BPF_NEG if dst is a pointer\n\nIn check_alu_op(), the verifier currently calls check_reg_arg() and\nadjust_scalar_min_max_vals() unconditionally for BPF_NEG operations.\nHowever, if the destination register holds a pointer, these scalar\nadjustments are unnecessary and potentially incorrect.\n\nThis patch adds a check to skip the adjustment logic when the destination\nregister contains a pointer.","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: Skip scalar adjustment for BPF_NEG if dst is a pointer","id":"CVE-2025-40050","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"vhost: vringh: Modify the return value check","id":"CVE-2025-40051"},"packages":[],"prev":{"headline":"Squashfs: fix uninit-value in squashfs_get_parent","id":"CVE-2025-40049"},"products":["Linux"],"published":"2025-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A flaw in the Linux kernel BPF verifier allows incorrect scalar adjustments for pointer registers, potentially enabling privilege escalation or code execution.","url":"https://insights.sbomify.com/CVE-2025-40050/"}
