Use after free in Dawn in Google Chrome prior to 146.0.7680.178 allowed a remote attacker who had compromised the renderer process to execute arbitrary code via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome prior to 146.0.7680.178 via use-after-free vulnerability in Dawn graphics subsystem allows an attacker who has already compromised the renderer process to execute arbitrary code through a crafted HTML page. This vulnerability requires prior renderer compromise but presents significant risk in multi-process exploitation chains; vendor has released patched version 146.0.7680.178 to address the issue.
Technical ContextAI
The vulnerability exists in Dawn, Google Chrome's graphics abstraction layer (WebGPU implementation), which handles GPU-related operations and memory management. The use-after-free condition (CWE-416) occurs when the renderer process attempts to access memory that has been freed, typically in graphics command processing or resource cleanup routines. Dawn operates within Chrome's renderer process sandbox; exploitation requires an attacker to first compromise the renderer process itself through an initial vulnerability (such as a separate memory safety flaw), then leverage this use-after-free to break out or escalate privileges. The CPE indicates all Chrome versions prior to 146.0.7680.178 are affected across all platforms where Chrome runs.
RemediationAI
Vendor-released patch: upgrade to Google Chrome 146.0.7680.178 or later. Users should enable automatic updates to receive this patch; manual update can be performed by navigating to Chrome Settings > About > Check for updates. Enterprise administrators deploying Chrome should update all instances to 146.0.7680.178 or a later stable release version. No workaround is available for this vulnerability short of patching, as the flaw is in core graphics processing logic. Detailed patch information is available in the Chromium issue tracker (https://issues.chromium.org/issues/492139412) and the Chrome stable channel release notes (http://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_31.html).
