Out of bounds read in ANGLE in Google Chrome on Linux prior to 149.0.7827.53 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds read in ANGLE (Google's graphics abstraction layer) within Chrome on Linux exposes sensitive process memory to remote attackers via a crafted HTML page. All Chrome for Linux versions prior to 149.0.7827.53 are affected; Windows and macOS are not in scope. The CVSS vector confirms unauthenticated remote exploitability at low complexity, though user interaction is required, and no public exploit has been identified at time of analysis - EPSS at 0.03% (11th percentile) signals minimal current exploitation pressure.
Technical ContextAI
ANGLE (Almost Native Graphics Layer Engine) is Google's open-source graphics abstraction library that translates OpenGL ES API calls into platform-native graphics APIs such as Vulkan on Linux. CWE-125 (Out-of-Bounds Read) identifies the root cause: a memory safety defect where the ANGLE subsystem reads data beyond the boundary of an allocated buffer during HTML page rendering. On Linux, ANGLE directly mediates GPU-accelerated content rendering in Chrome, making it reachable from web content. This class of flaw in a graphics pipeline is significant because renderer process memory may contain sensitive user data - rendered text, decoded media, DOM content, or authentication tokens - that could be disclosed without triggering a crash or alerting the user. No CPE strings were provided in the source data; affected scope is inferred from the ENISA EUVD record (EUVD-2026-34500) as Chrome < 149.0.7827.53 on Linux.
RemediationAI
Update Google Chrome on Linux to version 149.0.7827.53 or later - this is the vendor-released patch confirmed in the Chrome stable channel advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Chrome typically applies updates automatically on next browser restart; administrators managing enterprise Linux fleets via policy should verify enforcement of the minimum version. For environments where immediate patching is blocked, the practical compensating control is user-level: restrict access to untrusted or unknown external web content, since exploitation requires the victim to visit a crafted HTML page (UI:R). This is a partial mitigation only, as it relies on user behavior and does not eliminate the vulnerability. No configuration toggle or feature-disablement is known to neutralize ANGLE rendering in standard Chrome deployments without severely degrading browser functionality.
