Out of bounds read in ANGLE in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to read memory outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Out-of-bounds read in ANGLE (Chrome's OpenGL ES translation layer) in Google Chrome prior to 153.0.8010.36 enables a remote unauthenticated attacker to read limited memory content outside the renderer sandbox by luring a user to a crafted HTML page. Unlike co-patched ANGLE issues in the same Chrome 153.0.8010.36 release that achieve full sandbox escape and remote code execution, this flaw is bounded to confidentiality impact only with no scope change - the read does not escape the renderer process. …

Vulnerability AssessmentAI

Exploitation The sole prerequisite is that a user visits an attacker-controlled or compromised web page using a vulnerable version of Google Chrome (any version prior to 153.0.8010.36); the CVSS vector AV:N/AC:L/PR:N/UI:R confirms network delivery with no authentication and no special configuration required. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N accurately reflects the real-world profile of this vulnerability: network-reachable with no privilege or complexity barriers, but requiring user interaction and yielding only limited confidentiality impact without scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Vendor-released patch: Chrome 153.0.8010.36, which resolves this vulnerability as confirmed by the Chrome stable channel advisory at chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html. … Detailed patch versions, workarounds, and compensating controls in full report.
