Use-after-free in Qualcomm Adreno GPU drivers in Chrome

IdentifiersCVE-2025-27038CWE-416· Use After Free

CVE-2025-27038 is a use-after-free vulnerability in Qualcomm Graphics / Adreno GPU user-land driver components that can trigger memory corruption while rendering graphics in Chrome. The provided content specifically describes the issue as occurring in Adreno GPU drivers during Chrome graphics rendering, and more detailed reporting states it is a Qualcomm Adreno GPU user-land library UAF reachable via WebGL, including a crafted glFenceSync call. Google TAG indicated the flaw was under limited, targeted exploitation, and GTIG reported it was observed exploited in the wild as part of an exploit chain with Chrome renderer CVE-2024-0519 and KGSL driver CVE-2023-33106.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can cause memory corruption in the Adreno graphics stack and may enable code execution or sandbox escape when chained with other vulnerabilities. The supplied content indicates in-the-wild exploitation in targeted attacks and specifically notes chaining with a Chrome renderer bug and a KGSL driver flaw. In practical terms, exploitation can provide an attacker a path from a compromised or attacker-controlled Chrome rendering context into more privileged GPU/OS components, potentially contributing to device compromise.

Mitigation

If you can’t patch tonight, do this now.

Until patches are fully deployed, reduce exposure by limiting use of untrusted content in Chrome on affected Android devices, prioritizing patching of devices with Qualcomm chipsets, and enforcing rapid mobile update compliance through MDM or equivalent fleet management. Because the issue is associated with Chrome graphics rendering and WebGL-reachable GPU functionality, restricting exposure to untrusted web content and disabling or limiting risky browser features where operationally feasible may reduce attack surface, but patching is the primary mitigation.

Remediation

Patch, then assume compromise.

Apply vendor patches that address CVE-2025-27038. The content states Qualcomm disclosed and patched the issue in 2025, provided fixes to OEMs in May 2025, and Google included fixes in Android security updates released in August 2025. Organizations should deploy the relevant Android security update level and any OEM firmware updates incorporating Qualcomm’s Adreno driver fixes as soon as they are available.
