CVE-2026-7357
Published: 28 April 2026
Summary
CVE-2026-7357 is a high-severity Use After Free (CWE-416) vulnerability in Google Chrome. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Drive-by Compromise (T1189); ranked at the 6.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the use-after-free vulnerability in Chrome's GPU by requiring timely installation of patches like version 147.0.7727.138.
Implements memory protections such as heap hardening, ASLR, and isolation techniques that directly counter use-after-free heap corruption in the GPU process.
Isolates the GPU process from the compromised renderer, limiting the attacker's ability to trigger heap corruption via inter-process communication from crafted HTML.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The use-after-free in Chrome's GPU component is triggered via a crafted HTML page on a malicious site (enabling T1189 drive-by compromise) and allows heap corruption for code execution in the client browser (T1203), though the 'already compromised renderer' phrasing introduces some uncertainty about whether this is a primary or secondary exploit.
NVD Description
Use after free in GPU in Google Chrome prior to 147.0.7727.138 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
Deeper analysisAI
CVE-2026-7357 is a use-after-free vulnerability (CWE-416) in the GPU component of Google Chrome prior to version 147.0.7727.138. Published on 2026-04-28, it enables potential heap corruption and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H), rated as High severity by the Chromium security team.
The vulnerability can be exploited by a remote attacker who has already compromised the renderer process, using a crafted HTML page to trigger heap corruption. Attackers require network access with no privileges but must achieve high-complexity execution and rely on user interaction, such as visiting a malicious site. Successful exploitation could result in high impacts to confidentiality, integrity, and availability.
Google's stable channel update for desktop, announced at https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop_28.html, addresses the issue in Chrome 147.0.7727.138 and later versions. Further technical details are documented in the Chromium issue tracker at https://issues.chromium.org/issues/497047552.
