Uninitialized Use in Dawn in Google Chrome prior to 150.0.7871.46 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Uninitialized memory exposure in Google Chrome's Dawn WebGPU component (versions prior to 150.0.7871.46) allows remote attackers to read potentially sensitive data from the Chrome renderer process. Exploitation requires a victim to visit a crafted HTML page, after which residual process memory - potentially containing credentials, session tokens, or other in-memory secrets - may be disclosed to the attacker. No public exploit identified at time of analysis; EPSS of 0.20% (10th percentile) and SSVC exploitation status of 'none' confirm low immediate exploitation likelihood despite the medium-severity CVSS rating.
Technical ContextAI
Dawn is Google's open-source, cross-platform implementation of the WebGPU API, used as the GPU backend within Chrome's renderer process. CWE-457 (Use of Uninitialized Variable) indicates that a buffer or variable within Dawn's code is read before it is properly zeroed or assigned, causing residual heap or stack data from prior allocations to be accessible. This class of flaw is particularly common in graphics and GPU driver code where performance-sensitive memory management routinely skips zero-initialization. The affected product is identified by CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*, covering all platform variants of Chrome prior to 150.0.7871.46. The ENISA EUVD entry EUVD-2026-41193 independently corroborates the affected version boundary.
RemediationAI
The primary fix is upgrading Google Chrome to version 150.0.7871.46 or later, as confirmed by the vendor advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. Chrome's built-in auto-update mechanism will apply this fix automatically in most consumer and unmanaged enterprise deployments; administrators should verify the installed version via chrome://settings/help. Enterprises using managed update policies (Google Admin Console, Chromebook EMM, or SCCM/Intune for Chrome) should push the stable channel update containing 150.0.7871.46. SUSE users should monitor their vendor's security advisories for patched Chromium packages. No viable workaround short of upgrading exists - disabling WebGPU/Dawn would break an increasing share of modern web content and is not recommended as a compensating control in most environments. Patch availability per vendor advisory is confirmed; exact fix version 150.0.7871.46 is independently corroborated by EUVD data.
