It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-5427 exists.\n\nAffected product: Arm Valhall Gpu Kernel Driver. 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-2023-5427/ (Markdown: https://insights.sbomify.com/CVE-2023-5427/index.md)","id":"CVE-2023-5427","markdown":"https://insights.sbomify.com/CVE-2023-5427/index.md","name":"CVE-2023-5427","record":{"aliases":["A-308188337","ASB-A-308188337","GHSA-jrr9-w96c-8wpv"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mali GPU Kernel Driver","requires_auth":"low_privilege","summary":"A local attacker can exploit a use-after-free flaw in Mali GPU kernel drivers to access freed memory, potentially leading to privilege escalation or data exposure.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arm","cpe":[{"product":"5th_gen_gpu_architecture_kernel_driver","vendor":"arm"},{"product":"bifrost_gpu_kernel_driver","vendor":"arm"},{"product":"valhall_gpu_kernel_driver","vendor":"arm"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","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-416","name":"Use After Free"}],"description":"Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user to make improper GPU processing operations to gain access to already freed memory.This issue affects Bifrost GPU Kernel Driver: from r44p0 through r45p0; Valhall GPU Kernel Driver: from r44p0 through r45p0; Arm 5th Gen GPU Architecture Kernel Driver: from r44p0 through r45p0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Mali GPU Kernel Driver allows improper GPU processing operations","id":"CVE-2023-5427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"arm:valhall_gpu_kernel_driver","products":["arm:valhall_gpu_kernel_driver"],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Image vertical reel scroll slideshow \u003c= 9.0 - Authenticated (Subscriber+) SQL Injection via Shortcode","id":"CVE-2023-5428"},"packages":[],"prev":{"headline":"Post Meta Data Manager \u003c=1.2.0 - Missing Authorization to User, Term, and Post Meta Deletion","id":"CVE-2023-5426"},"products":["Arm 5th Gen GPU Architecture Kernel  Driver","Bifrost GPU Kernel Driver","Valhall GPU Kernel Driver"],"published":"2023-12-01","related":[{"cvss_score":5.5,"headline":"Arm Mali GPU Kernel Driver Use-After-Free","id":"CVE-2023-4211","kev_date_added":"2023-10-03","published":"2023-10-01"},{"cvss_score":3.3,"headline":"Arm Mali GPU Kernel Driver Information Disclosure","id":"CVE-2023-26083","kev_date_added":"2023-04-07","published":"2023-04-06"},{"cvss_score":8.4,"headline":"Mali GPU Kernel Driver allows improper GPU memory processing operations","id":"CVE-2023-6143","kev_date_added":null,"published":"2024-03-04"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows improper GPU memory processing operations","id":"CVE-2025-0073","kev_date_added":null,"published":"2025-06-02"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows access to already freed memory","id":"CVE-2025-0819","kev_date_added":null,"published":"2025-06-02"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows improper GPU memory processing operations","id":"CVE-2025-0072","kev_date_added":null,"published":"2025-05-02"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows access to already freed memory","id":"CVE-2025-0427","kev_date_added":null,"published":"2025-05-02"}],"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)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-25","vendors":["Arm Ltd"]},"summary":"A local attacker can exploit a use-after-free flaw in Mali GPU kernel drivers to access freed memory, potentially leading to privilege escalation or data exposure.","url":"https://insights.sbomify.com/CVE-2023-5427/"}
