12 New Chrome Vulnerabilities - 8 Critical, 4 High Severity

Sandbox escape in Google Chrome desktop prior to 151.0.7922.72 lets an attacker who has already compromised the renderer process leverage a use-after-free in the Audio component to break out of the sandbox via a crafted HTML page. Rated High by Chromium and CVSS 9.6 due to scope change, this is a second-stage exploit primitive rather than an initial-access bug; no public exploit has been identified at time of analysis and EPSS is low at 0.29%. A vendor patch is available in Chrome 151.0.7922.72.

Sandbox escape in Google Chrome's ANGLE graphics layer affects all desktop builds prior to 151.0.7922.72, where an integer overflow can be triggered by a crafted HTML page to potentially break out of the renderer sandbox. Reported internally by the Chrome team and rated High by Chromium, with a vendor patch already shipped in the stable channel; no public exploit identified at time of analysis and EPSS exploitation probability is low (0.29%, 21st percentile). Because sandbox escapes in ANGLE are typically chained with a renderer bug, this is a high-value component of a full-chain browser exploit rather than a standalone remote code execution.

Sandbox escape in Google Chrome's media codec handling affects all Chrome desktop builds prior to 151.0.7922.72, where an integer overflow while parsing a maliciously crafted video file can let a remote attacker break out of the renderer sandbox. Exploitation requires the victim to load attacker-controlled media (UI:R), and there is no public exploit identified at time of analysis; EPSS is low (0.17%, 6th percentile) and the flaw is not on CISA KEV. Notably, Chromium's own triage rated this 'Medium' severity, which conflicts with the NVD-style 9.6 Critical score.

Sandbox escape in Google Chrome for Android before 151.0.7922.72 stems from insufficient input validation in Dawn, Chromium's WebGPU implementation, and allows a remote attacker who lures a victim to a crafted HTML page to potentially break out of the renderer/GPU-process sandbox (CVSS 9.6, scope-changed). There is no public exploit identified at time of analysis and the flaw is not in CISA KEV; EPSS is low at 0.31% (23rd percentile), consistent with SSVC rating exploitation as 'none' despite a 'total' technical impact. Chrome rates the underlying Chromium bug as Critical.

Sandbox escape in Google Chrome for Android before 151.0.7922.72 lets an attacker who already controls a compromised renderer process break out of the sandbox through crafted input handled by the browser's Accessibility component. Rated High by Chromium and CVSS 9.6, it is a second-stage bug typically chained after an initial renderer exploit, giving an attacker a path to full compromise of the browser/host context. There is no public exploit identified at time of analysis, EPSS risk is low (0.29%, 21st percentile), and it is not on CISA KEV.

Sandbox escape in Google Chrome's ANGLE graphics layer, fixed in stable release 151.0.7922.72, lets a remote attacker who lures a victim to a crafted HTML page break out of the renderer sandbox and gain broader access on the host. Rated Critical by Chromium and scored CVSS 9.6, the flaw stems from insufficient validation of untrusted input (CWE-20) processed by ANGLE and carries a scope-changing impact. There is no public exploit identified at time of analysis and EPSS is low at 0.31% (23rd percentile), but the Critical rating and sandbox-escape primitive make prompt patching important.

Sandbox escape in Google Chrome's ANGLE graphics layer on macOS (versions prior to 151.0.7922.72) lets an attacker who has already compromised the renderer process break out of the browser sandbox via a crafted HTML page. Rated High by Chromium and carrying a CVSS 9.6 due to the scope change from renderer to host, it enables full compromise of the browser process. There is no public exploit identified at time of analysis and it is not on CISA KEV; EPSS is low at 0.29% (21st percentile).

Sandbox escape in Google Chrome's ANGLE graphics layer on Android (versions prior to 151.0.7922.72) allows a remote attacker who has already compromised the renderer process to break out of the renderer sandbox and gain broader access on the device via a crafted HTML page. Rated High by Chromium and scored CVSS 9.6 largely because of the scope change from a successful escape. There is no public exploit identified at time of analysis, and EPSS is low (0.29%, 21st percentile), consistent with a bug that only becomes useful after a prior renderer compromise.
