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-2021-31795 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-31795/ (Markdown: https://insights.sbomify.com/CVE-2021-31795/index.md)","id":"CVE-2021-31795","markdown":"https://insights.sbomify.com/CVE-2021-31795/index.md","name":"CVE-2021-31795","record":{"aliases":["GHSA-fwhm-xh8g-8m5q"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PowerVR GPU driver","requires_auth":"low_privilege","summary":"Attackers can overwrite heap memory in the PowerVR GPU kernel driver, potentially leading to code execution or privilege escalation on affected Linux devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pvrsrvkm.ko","vendor":"pvrsrvkm.ko_project"}],"cvss":{"score":7,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/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":"The PowerVR GPU kernel driver in pvrsrvkm.ko through 2021-04-24 for the Linux kernel, as used on Alcatel 1S phones, allows attackers to overwrite heap memory via PhysmemNewRamBackedPMR.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2021-31795","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2021-31796"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-31794"},"products":["n/a"],"published":"2021-04-24","related":[],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can overwrite heap memory in the PowerVR GPU kernel driver, potentially leading to code execution or privilege escalation on affected Linux devices.","url":"https://insights.sbomify.com/CVE-2021-31795/"}
