CVE-2026-11682: Inappropriate implementation in Views in Google Chrome on Linux prior to 149

Synopsis

This is a sandbox escape vulnerability in Google Chrome's Views component on Linux, affecting all versions prior to 149.0.7827.103. The flaw is reachable over the network but requires the attacker to have already compromised the renderer process and to trick a user into visiting a crafted HTML page. Successful exploitation allows the attacker to break out of Chrome's sandbox, gaining the ability to read files, modify data, or disrupt processes on the underlying host. A patched-image rebuild at version 149.0.7827.103 is available on HarborGuard for affected environments.

HarborGuard Coverage

Exploit Conditions

• Network reachabilityRequired

  The attacker must reach the victim over the network by serving a crafted HTML page, making the service's network exposure a prerequisite.

• AuthenticationNot required

  No account or credentials are needed to deliver the malicious page to the victim's browser.

• Victim interactionRequired

  The victim must visit a crafted HTML page, meaning the attacker must use a social-engineering or drive-by delivery mechanism to lure the user.

• Attack complexityDetail

  Exploitation is rated high complexity because the attacker must have already compromised the renderer process before attempting the sandbox escape, introducing a significant precondition.

Blast Radius

• A successful attacker escapes Chrome's sandbox and gains code execution in the context of the browser process on the Linux host.
• Confidentiality impact is high: the attacker can read files and data accessible to the browser process, including cached credentials or session tokens stored on disk.
• Integrity impact is high: the attacker can write or modify files and persistent data on the host outside the sandbox boundary.
• Availability impact is high: the attacker can crash or disrupt the browser process and potentially other processes accessible from the escaped sandbox context.
