CISA KEV Advisory
Arm Mali GPU Kernel Driver Unspecified Vulnerability
Arm Mali GPU Kernel Driver contains an unspecified vulnerability that allows a non-privileged user to achieve write access to read-only memory pages.
Apply updates per vendor instructions.
Risk Analysis
This high-severity vulnerability in Arm Mali GPU Kernel Driver allows a non-privileged user to gain write access to read-only memory pages. This could lead to various security compromises, including privilege escalation. The confirmed exploitation by CISA (is_in_kev: true) highlights its critical nature despite the lack of a CVSS score.
Active exploitation of this vulnerability has been observed in the wild. This indicates that attackers are actively leveraging this flaw.
Apply the latest security updates and patches for Arm Mali GPU Kernel Driver. Regularly monitor for and install updates from the vendor to mitigate such kernel-level vulnerabilities.
Technical Analysis
CVE-2022-22706 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2022-22706 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
