What we know

• CVE-2025-10500 is a use-after-free flaw in Dawn, a graphics abstraction layer used by Chrome/WebGPU. CyberInsider+2Daily CyberSecurity+2
• Discovered by researcher Gyujeong Jin (Giunash), reported on ~August 3, 2025. Daily CyberSecurity+1
• Classified as High severity. It may lead to memory corruption, crashes, or worse (arbitrary code execution) depending on exploit chaining and sandbox bypasses. Daily CyberSecurity+2CyberInsider+2

Why this matters

• Dawn/WebGPU is part of modern browser / GPU stack exposing graphics capabilities. Vulnerabilities there can be leveraged via malicious sites or crafted content.
• Use-after-free implies memory region being used after its freed — can enable remote attackers (via malicious web content) to corrupt memory, possibly lead to code execution.
• If exploited successfully, could lead to sandbox escape or privilege escalation within Chrome or any host that uses Dawn.

Affected Software / Versions

• Chrome versions before patch (after release including fix for this CVE) Daily CyberSecurity+2Cyber Security News+2
• All major platforms: Windows, macOS, Linux via the Chrome browser. WebGPU / Dawn enabled environments. Daily CyberSecurity+1

Detection & Hunting Tips

Here are signs to monitor:

• Crash logs / renderer process instability relating to Dawn/WebGPU (look for stack traces referencing Dawn or WebGPU abstractions).
• Browser error/sandbox escape attempts following rendering tasks (e.g., after WebGPU shaders or GPU-accelerated content).
• Unusual GPU driver or graphics component logs.
• Monitor for unusual memory allocation/free patterns or UAF indicators in Chrome or GPU logs.

Sample query pseudo-logic:

index=chrome_crash_logs
| where crash_reason contains "use after free" OR module contains "dawn" AND crash_stack contains WebGPU
| stats count by host, version, stack_trace

Mitigation & Fixes

Immediate actions

• Update Chrome immediately to the patched version. Google released updates in stable channel that incorporate the fix for this CVE. Daily CyberSecurity+1
• If you have browsers or environments with WebGPU disabled or Dawn not in use, consider disabling or restricting WebGPU until patch is confirmed.

Medium term / best practices

• Harden sandbox and isolate GPU processes. Ensure graphics processes run with least privilege.
• Enable site isolation and enforce safe content policies for untrusted sites.
• Monitor for new versions of browser builds and ensure patch management is in place.

Risk & Exploitability

• Exploit complexity: requires crafting web content or malware to trigger use-after-free in Dawn. Not trivial, but realistic especially when combined with other bugs.
• User interaction: likely requires visiting a malicious website or opening malicious content; may not be full drive-by unless picked carefully.

Recommendations

• Ensure all browsers in your organization are updated to the version that patches CVE-2025-10500.
• For any WebGPU-heavy web apps or sandboxed GPU content, test under patched and unpatched conditions to see behavior.
• Audit clients / endpoints for GPU driver versions; ensure compatibility with updated Chrome graphics stack.
• Train incident responders to collect GPU crash dumps and browser renderer logs (forensics) in case of suspected exploit.
