- Potentially affects user systems.
- Requires visiting a malicious page.
- High impact if exploited.
Attack Path
How an attacker could exploit the issue
An attacker can exploit this flaw by tricking a user into visiting a specially crafted HTML page. This page would then trigger a use-after-free vulnerability in Chrome's GPU process. Successfully exploiting this could allow the attacker to break out of the browser's sandbox and potentially gain elevated privileges on the victim's system.
- Requires user interaction.
- Targets GPU component.
- Allows sandbox escape.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability, a use-after-free in Chrome's GPU component, could allow a remote attacker to escape the sandbox via a crafted HTML page. While it requires user interaction and is not internet-facing, sandbox escapes are valuable for attackers aiming to gain deeper system access. The absence of active exploitation signals or public proof-of-concept code suggests it has not yet been widely weaponized.
- No known public exploits.
- No KEV listing.
- Vulnerability discovered recently.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Focus on identifying and isolating affected Chrome instances immediately, as this vulnerability allows for sandbox escapes. Prioritize patching to version 147.0.7727.138 or later for all systems to remediate this critical risk.
- Patch Chrome to 147.0.7727.138 or later.
