An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-2163 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2023-2163/ (Markdown: https://insights.sbomify.com/CVE-2023-2163/index.md)","id":"CVE-2023-2163","markdown":"https://insights.sbomify.com/CVE-2023-2163/index.md","name":"CVE-2023-2163","record":{"aliases":["AZL-29941","DEBIAN-CVE-2023-2163","SUSE-SU-2023:4835-1","UBUNTU-CVE-2023-2163"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux Kernel","requires_auth":"none","summary":"Incorrect BPF verifier pruning allows arbitrary kernel memory read/write, enabling privilege escalation and container escape.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-682","name":"Incorrect Calculation"}],"description":"Incorrect verifier pruning in BPF in Linux Kernel \u003e=5.4 leads to unsafe\ncode paths being incorrectly marked as safe, resulting in arbitrary read/write in\nkernel memory, lateral privilege escalation, and container escape.","ecosystems":["SUSE:Linux Enterprise Live Patching 15 SP2"],"exploits":{"exploitdb":0,"first_seen":"2024-11-27","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-11-27T16:25:48Z","kind":"github_poc","ref":"https://github.com/letsr00t/CVE-2023-2163","stars":1,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Incorrect Verifier Branch Pruning Logic Leads To Arbitrary Read/Write In Linux Kernel and Lateral Privilege Escalation","id":"CVE-2023-2163","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"privilege_escalation","year":"2023"},"n_packages":1,"n_references":1,"next":{"headline":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in GitLab","id":"CVE-2023-2164"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Live Patching 15 SP2","fixed":["3-150200.2.1"],"introduced":["0"],"last_affected":[],"package":"kernel-livepatch-SLE15-SP2_Update_41","purl":"pkg:rpm/suse/kernel-livepatch-SLE15-SP2_Update_41\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2015%20SP2","source":"SUSE-SU-2023:4835-1"}],"prev":{"headline":"Use after free in Kernel","id":"CVE-2023-2162"},"products":["Linux Kernel"],"published":"2023-09-20","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-27","vendors":["Linux"]},"summary":"Incorrect BPF verifier pruning allows arbitrary kernel memory read/write, enabling privilege escalation and container escape.","url":"https://insights.sbomify.com/CVE-2023-2163/"}
