Google Chrome patched two high-severity heap buffer overflow vulnerabilities, CVE-2026-5272 in the browser's GPU component and CVE-2026-5275 in ANGLE, that could allow remote arbitrary code execution if a user opened a crafted HTML page. Both flaws are classified as CWE-122 and carry a CVSS v3.1 rating of AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, reflecting low attack complexity and high potential impact to confidentiality, integrity, and availability.
The issues affect Google Chrome versions prior to 146.0.7680.178, with impacted platforms listed across Windows, Linux, and macOS, while the ANGLE flaw was specifically described as affecting Chrome on Mac. The vulnerabilities were referenced in Google's Chrome stable channel advisory and Chromium issue tracker, underscoring the need for organizations to update browsers promptly to the patched release to reduce exposure to malicious web content.

Google Chrome addressed two high-severity heap buffer overflow vulnerabilities that could be used to help break out of the browser sandbox. **CVE-2026-6296** affects **ANGLE** in Chrome versions prior to `147.0.7727.101` and could allow a remote attacker to potentially achieve a sandbox escape by luring a user to a crafted HTML page. The flaw is tracked as **CWE-122** and carries a `CVSS:3.1` vector of `AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`, indicating high impact across confidentiality, integrity, and availability. Google also fixed **CVE-2026-7353**, a separate **Skia** heap buffer overflow affecting Chrome versions prior to `147.0.7727.138`. Chromium rated the issue as high severity and said a remote attacker who had already compromised the renderer process could potentially use a crafted HTML page to achieve a sandbox escape. The bug is also classified as **CWE-122** and was assigned the `CVSS:3.1` vector `AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H`. Google linked both issues to Chrome release notes and Chromium issue tracker entries as part of the remediation.

Google released security updates for Chrome 149 to fix multiple vulnerabilities affecting Windows, macOS, and Linux, warning that successful exploitation could lead to spoofing, denial of service, memory corruption, information disclosure, security bypass, or arbitrary code execution via a crafted HTML page. The June 7 advisory identified Chrome `149.0.7827.53/54` for Windows and macOS and `149.0.7827.53` for Linux as the patched versions. The update notably addressed **CVE-2026-10881**, an out-of-bounds read/write flaw in **ANGLE**, and **CVE-2026-11250**, an inappropriate implementation issue in **DevTools**; both were highlighted with a **CVSS 9.6** severity rating. A follow-on Chrome security update notice was also issued on June 14, reinforcing the need for organizations to validate and deploy the latest browser patches promptly after testing.

Google released a Chrome Stable channel update to fix 15 security issues, including the critical vulnerability **CVE-2026-76034** in **WebGL**. The flaw is a `CWE-122` buffer overflow affecting Chrome versions prior to **151.0.7922.169**, and Google said it could be triggered by malicious web content. The update was issued as **151.0.7922.169/.170** for Windows and macOS and **151.0.7922.169** for Linux, with rollout occurring gradually. According to the CVE record, **CVE-2026-76034** could let a remote attacker execute arbitrary code outside the browser sandbox by persuading a user to open a crafted HTML page. Google also disclosed a second critical buffer overflow, **CVE-2026-76036**, in **Dawn**, Chromium’s WebGPU implementation, but said detailed technical information and bug reports are being withheld until most users have installed the fixes to reduce the risk of weaponization through patch reverse engineering.
