The Arm Mali GPU kernel driver allows unprivileged users to access freed memory because GPU memory operations are mishandled. This affects Bifrost r0p0 through r38p1, and r39p0; Valhall r19p0 through r38p1, and r39p0; and Midgard r4p0 through r32p0.
Conclusion & alert: CVE-2022-38181 is rated Critical Active Threat (88.7/100): CVSS High severity, with high exploitation likelihood (EPSS 12.59%, 96th percentile). Core evidence: CISA KEV confirms active exploitation (added 2023-03-30) affecting Arm / Mali Graphics Processing Unit (GPU). a weakness (CWE-416) Unauthenticated remote administrative access may be possible. Mandatory action: The CISA remediation deadline has passed—treat as an emergency patch priority.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
