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-2021-26391 in the wild and no public exploit code.\n\nAffected product: Amd Radeon Software. 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-2021-26391/ (Markdown: https://insights.sbomify.com/CVE-2021-26391/index.md)","id":"CVE-2021-26391","markdown":"https://insights.sbomify.com/CVE-2021-26391/index.md","name":"CVE-2021-26391","record":{"aliases":["GHSA-cm49-fh74-75ch"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD Radeon GPU","requires_auth":"low_privilege","summary":"An attacker with privileges can bypass signature verification to execute arbitrary code in Trusted Applications or the kernel on AMD Radeon GPUs.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"enterprise_driver","vendor":"amd"},{"product":"radeon_pro_software","vendor":"amd"},{"product":"radeon_rx_vega_56_firmware","vendor":"amd"},{"product":"radeon_rx_vega_64_firmware","vendor":"amd"},{"product":"radeon_software","vendor":"amd"},{"product":"ryzen_3_5300g_firmware","vendor":"amd"},{"product":"ryzen_3_5300ge_firmware","vendor":"amd"},{"product":"ryzen_3_5300u_firmware","vendor":"amd"},{"product":"ryzen_3_5400u_firmware","vendor":"amd"},{"product":"ryzen_5_5500u_firmware","vendor":"amd"},{"product":"ryzen_5_5560u_firmware","vendor":"amd"},{"product":"ryzen_5_5600g_firmware","vendor":"amd"},{"product":"ryzen_5_5600ge_firmware","vendor":"amd"},{"product":"ryzen_5_5600h_firmware","vendor":"amd"},{"product":"ryzen_5_5600hs_firmware","vendor":"amd"},{"product":"ryzen_5_5600u_firmware","vendor":"amd"},{"product":"ryzen_7_5700g_firmware","vendor":"amd"},{"product":"ryzen_7_5700ge_firmware","vendor":"amd"},{"product":"ryzen_7_5700u_firmware","vendor":"amd"},{"product":"ryzen_7_5800h_firmware","vendor":"amd"},{"product":"ryzen_7_5800hs_firmware","vendor":"amd"},{"product":"ryzen_7_5800u_firmware","vendor":"amd"},{"product":"ryzen_9_5900hs_firmware","vendor":"amd"},{"product":"ryzen_9_5900hx_firmware","vendor":"amd"},{"product":"ryzen_9_5980hs_firmware","vendor":"amd"},{"product":"ryzen_9_5980hx_firmware","vendor":"amd"}],"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-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Insufficient verification of multiple header signatures while loading a Trusted Application (TA) may allow an attacker with privileges to gain code execution in that TA or the OS/kernel.","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":"Security feature bypass in AMD Radeon RX 5000 Series \u0026 PRO W5000 Series","id":"CVE-2021-26391","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"amd:radeon_software","products":["amd:radeon_software"],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in AMD Radeon RX 5000 Series \u0026 PRO W5000 Series","id":"CVE-2021-26392"},"packages":[],"prev":{"headline":"Memory corruption in Athlon™ Series","id":"CVE-2021-26390"},"products":["AMD Radeon RX 5000 Series \u0026 PRO W5000 Series","AMD Radeon RX 6000 Series \u0026 PRO W6000 Series"],"published":"2022-11-09","related":[{"cvss_score":7.8,"headline":"Privilege escalation in AMD Radeon RX 6000 Series \u0026 PRO W6000 Series","id":"CVE-2021-26360","kev_date_added":null,"published":"2022-11-09"}],"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-05-01","vendors":["AMD"]},"summary":"An attacker with privileges can bypass signature verification to execute arbitrary code in Trusted Applications or the kernel on AMD Radeon GPUs.","url":"https://insights.sbomify.com/CVE-2021-26391/"}
