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-2026-80524 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-2026-80524/ (Markdown: https://insights.sbomify.com/CVE-2026-80524/index.md)","id":"CVE-2026-80524","markdown":"https://insights.sbomify.com/CVE-2026-80524/index.md","name":"CVE-2026-80524","record":{"aliases":["BELL-CVE-2026-80524","DEBIAN-CVE-2026-80524","GHSA-7v3f-hf4p-6cvj","UBUNTU-CVE-2026-80524"],"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":"none","summary":"A missing NULL check in the Linux kernel's OP-TEE FFA driver can cause a null pointer dereference and system crash under memory pressure.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\noptee: ffa: Add NULL check in optee_ffa_lend_protmem\n\nSashiko (locally) reports a possible null dereference under memory\npressure due to the lack of validation of the allocated pointer.\n\nFix that by adding the missing check.","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":"optee: ffa: Add NULL check in optee_ffa_lend_protmem","id":"CVE-2026-80524","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"ASoC: SOF: ipc4-topology: Refresh copier IPC payload before widget setup","id":"CVE-2026-80525"},"packages":[],"prev":{"headline":"clk: spacemit: k3: set hdma clock as critical","id":"CVE-2026-80523"},"products":["Linux"],"published":"2026-08-26","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":"2026-10-15","vendors":["Linux"]},"summary":"A missing NULL check in the Linux kernel's OP-TEE FFA driver can cause a null pointer dereference and system crash under memory pressure.","url":"https://insights.sbomify.com/CVE-2026-80524/"}
