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-2023-6931 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2023-6931/ (Markdown: https://insights.sbomify.com/CVE-2023-6931/index.md)","id":"CVE-2023-6931","markdown":"https://insights.sbomify.com/CVE-2023-6931/index.md","name":"CVE-2023-6931","record":{"aliases":["AZL-32264","AZL-34869","BELL-CVE-2023-6931","DEBIAN-CVE-2023-6931","GHSA-xv88-q3gm-mmjp","UBUNTU-CVE-2023-6931"],"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 heap out-of-bounds write in the Linux kernel's Performance Events component allows local attackers to escalate privileges or execute code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"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":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.\n\nA perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().\n\nWe recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-01-05","github_poc":2,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-01-05T00:28:28Z","kind":"github_poc","ref":"https://github.com/K0n9-log/CVE-2023-6931","stars":2,"title":"CVE-2023-6931 kernel panic PoC"},{"date":"2026-09-22T14:02:28Z","kind":"github_poc","ref":"https://github.com/Yutori-Natsu/cve-2023-6931-pipa","stars":1,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Out-of-bounds write in Linux kernel's Performance Events system component","id":"CVE-2023-6931","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Use-after-free in Linux kernel's ipv4: igmp component","id":"CVE-2023-6932"},"packages":[],"prev":{"headline":"Improper Access Control in EuroTel ETL3100","id":"CVE-2023-6930"},"products":["Linux Kernel"],"published":"2023-12-19","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-14","vendors":["Linux"]},"summary":"A heap out-of-bounds write in the Linux kernel's Performance Events component allows local attackers to escalate privileges or execute code.","url":"https://insights.sbomify.com/CVE-2023-6931/"}
