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-2025-40121 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-2025-40121/ (Markdown: https://insights.sbomify.com/CVE-2025-40121/index.md)","id":"CVE-2025-40121","markdown":"https://insights.sbomify.com/CVE-2025-40121/index.md","name":"CVE-2025-40121","record":{"aliases":["BELL-CVE-2025-40121","DEBIAN-CVE-2025-40121","GHSA-7q66-w47h-g677","ROOT-OS-DEBIAN-11-CVE-2025-40121","ROOT-OS-DEBIAN-13-CVE-2025-40121","ROOT-OS-UBUNTU-2404-CVE-2025-40121","UBUNTU-CVE-2025-40121"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"high_privilege","summary":"A local attacker with high privileges can trigger out-of-bounds memory access in the Intel bytcr_rt5651 audio driver by passing invalid quirk options, potentially leading to code execution or system crash.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nASoC: Intel: bytcr_rt5651: Fix invalid quirk input mapping\n\nWhen an invalid value is passed via quirk option, currently\nbytcr_rt5640 driver just ignores and leaves as is, which may lead to\nunepxected results like OOB access.\n\nThis patch adds the sanity check and corrects the input mapping to the\ncertain default value if an invalid value is passed.","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":"ASoC: Intel: bytcr_rt5651: Fix invalid quirk input mapping","id":"CVE-2025-40121","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":8,"next":{"headline":"perf/x86/intel: Fix IA32_PMC_x_CFG_B MSRs access error","id":"CVE-2025-40122"},"packages":[],"prev":{"headline":"net: usb: asix: hold PM usage ref to avoid PM/MDIO + RTNL deadlock","id":"CVE-2025-40120"},"products":["Linux"],"published":"2025-11-12","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 local attacker with high privileges can trigger out-of-bounds memory access in the Intel bytcr_rt5651 audio driver by passing invalid quirk options, potentially leading to code execution or system crash.","url":"https://insights.sbomify.com/CVE-2025-40121/"}
