Google Chrome: Use of uninitialized resource in GPU component
Summary
A flaw in the GPU component of Google Chrome (CWE-908, use of uninitialized resource) allows a remote attacker to read memory outside the browser sandbox. The attack requires that a user visits a crafted HTML page. The CVSS 4.7 (medium) score reflects low confidentiality impact only, with no integrity or availability impact.
Affected
- Google Chrome prior to 157.0.8103.50 (per CVE description)
- Secondary sources report a different older-branch range (up to 157.0.8103.38); not verified against primary sources.
Fixed in
- Google Chrome 157.0.8103.50 or later (Windows, Mac, Linux, Android, per secondary reports of the Chrome release notes)
- Extended Stable 156.0.8078.96 for Windows and Mac is reported by secondary sources; not confirmed for this CVE in the advisory text.
Workaround
Unknown.
Exploitation
- Not known to be exploited in the wild.
- No public proof of concept found.
- Not listed in CISA KEV.
- The same Chrome release fixes a different, actively exploited zero-day (CVE-2026-125350), which must not be confused with this CVE.
Our recommendation
- Update Google Chrome to 157.0.8103.50 or later on all desktops and Android devices, ideally via MDM or EDR.
- Verify installed versions and force a browser relaunch, because the fix only takes effect after restart.
- Check the Chromium bug report for any precondition, such as a compromised renderer, before the final report.
- Prioritise this update in the next maintenance window, since the same release fixes an exploited zero-day.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
