CISA KEV Advisory
Qualcomm Multiple Chipsets Use of Out-of-Range Pointer Offset Vulnerability
Multiple Qualcomm chipsets contain a use of out-of-range pointer offset vulnerability due to memory corruption in Graphics while submitting a large list of sync points in an AUX command to the IOCTL_KGSL_GPU_AUX_COMMAND.
Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.
Risk Analysis
Multiple Qualcomm chipsets are affected by a use of out-of-range pointer offset vulnerability due to memory corruption in Graphics. This can occur when submitting a large list of sync points in an AUX command to the IOCTL_KGSL_GPU_AUX_COMMAND. This is a high-severity flaw with confirmed exploitation in the wild.
This vulnerability is actively exploited in the wild and is listed in CISA's KEV catalog, indicating confirmed real-world impact.
Users of devices with affected Qualcomm chipsets should apply all available security updates. Keep your device's firmware and operating system updated to mitigate this risk.
Technical Analysis
CVE-2023-33106 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-2023-33106 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.
