Google Chrome: Out-of-bounds write in GPU allows code execution
Summary
Google Chrome versions before 157.0.8103.50 contain an out-of-bounds write in the GPU component, which handles graphics rendering. A remote attacker can use a crafted HTML page to potentially execute arbitrary code outside the browser sandbox. The user must open the malicious page, and no authentication is needed. Google rates the severity as High; NVD analysis is still pending and no exploitation of this specific CVE is known.
Affected
- Google Chrome prior to 157.0.8103.50 (desktop and Android)
Fixed in
- Google Chrome 157.0.8103.50 or later (vendor release of November 9, 2026)
- Windows and Mac builds may show .51 in some reports; the vendor post is authoritative
- Extended Stable: fix status of version 156.0.8078.96 not confirmed
Workaround
- Unknown. No workaround is needed when the update is installed; update Chrome and restart the browser.
Exploitation
- Not known to be exploited (this CVE), as of the sources reviewed.
- A different flaw, CVE-2026-125350 (use-after-free in XML), in the same release is reported as exploited in the wild and must not be confused with this CVE.
- No public proof of concept known; Google restricts technical details until most users are updated.
Our recommendation
- Update Google Chrome to 157.0.8103.50 or later on all desktop and Android endpoints now.
- Verify the version on managed devices and restart the browser, since the rollout is staged.
- Check Extended Stable and offline or pinned devices separately.
- Monitor for the separate exploited CVE-2026-125350 and apply the same update.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
