| CVE-2025-21479 | Incorrect Authorization in Qualcomm GPU Firmware Across Multiple Chipsets CVE-2025-21479 is an incorrect authorization flaw (CWE-863) in Qualcomm chipset firmware that allows unauthorized command execution in a GPU micronode, causing memory corruption when the GPU processes a specific sequence of commands. Because the CVSS vector is local (AV:L) with user interaction required, exploitation most plausibly involves a malicious local application or process driving the GPU through the vulnerable command sequence. An attacker who successfully triggers the flaw gains high-impact confidentiality, integrity, and availability effects with scope change, meaning the compromise can extend beyond the GPU component to the broader device. Affected products span Qualcomm AQT1000, FastConnect 6200/6700/6800/6900/7800, QCA6391, QCM4490, QCS4490, Snapdragon 855 (SD855), SM4635, and SM6250 firmware, i.e., chipsets used in Android smartphones and IoT/industrial devices. The flaw is being actively exploited: CISA added it to the Known Exploited Vulnerabilities catalog on 2025-06-03, and news reports describe limited, targeted Android attacks exploiting Qualcomm GPU zero-days fixed in Google's 2025 Android security updates. Do: Apply Qualcomm's fix by installing the Android security update from June 2025 or later (or the OEM/vendor firmware update for QCM4490, QCS4490, FastConnect, and other affected chipsets), checking your device's security patch level and chipset firmware against Qualcomm's bulletin, which lists the exact fixed versions. Organizations subject to BOD 22-01 must apply vendor mitigations per CISA's KEV required action or discontinue use of affected products; there is no known public PoC, but exploitation in targeted attacks is confirmed, so prioritize patching internet-facing and user-facing Android fleets. | 8.6 group max | <1% | KEV |

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Multiple Qualcomm chipsets flaws to its Known Exploited Vulnerabilities catalog.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added multiple Qualcomm chipsets flaws to its Known Exploited Vulnerabilities (KEV) catalog.
- CVE-2025-21479 Qualcomm Multiple Chipsets Incorrect Authorization Vulnerability
- CVE-2025-21480 Qualcomm Multiple Chipsets Incorrect Authorization Vulnerability
- CVE-2025-27038 Qualcomm Multiple Chipsets Use-After-Free Vulnerability
This week, Qualcomm addressed the above zero-day vulnerabilities that, according to the company, have been exploited in limited, targeted attacks in the wild.
Google Android Security team reported the three issues to the company.
“There are indications from Google Threat Analysis Group that CVE-2025-21479, CVE-2025-21480, CVE-2025-27038 may be under limited, targeted exploitation.” reads the report published by the vendor. “Patches for the issues affecting the Adreno Graphics Processing Unit (GPU) driver have been made available to OEMs in May together with a strong recommendation to deploy the update on affected devices as soon as possible.”
Below are the descriptions of these vulnerabilities:
- CVE-2025-21479 (CVSS score: 8.6) – The flaw is an Incorrect Authorization issue in the Graphics component. “Memory corruption due to unauthorized command execution in GPU micronode while executing specific sequence of commands.” reads the advisory.
- CVE-2025-21480 (CVSS score: 8.6) – The flaw is an Incorrect Authorization issue in Graphics Windows. “Memory corruption due to unauthorized command execution in GPU micronode while executing specific sequence of commands.” reads the advisory.
- CVE-2025-27038 (CVSS score: 7.5) – The flaw is a use-after-free issue in the Graphics component. “Memory corruption while rendering graphics using Adreno GPU drivers in Chrome.” states the advisory.
The company did not share details about the attacks exploiting the three vulnerabilities.
According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.
Experts also recommend private organizations review the Catalog and address the vulnerabilities in their infrastructure.
CISA orders federal agencies to fix the vulnerabilities by June 24, 2025.
