Google Chrome: Use-after-free in Media allows code execution in sandbox
Summary
A use-after-free flaw in the Media component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs only to lure a user to a crafted HTML page, and no authentication is required. A sandbox escape would be needed for full system compromise.
Affected
- Google Chrome prior to 155.0.8059.79
Fixed in
- Google Chrome 155.0.8059.79 and later (Windows, macOS, Linux)
- Debian bookworm chromium: 155.0.8059.79-1~deb12u1
- Ubuntu: update the Chromium snap, as the chromium-browser package is not affected
Workaround
- No workaround is needed when a patch is available. Patching is the only reliable mitigation.
- If patching is delayed, enforce automatic updates and restart the browser, as updates apply only after relaunch.
- No vendor-recommended interim workaround is known.
Exploitation
- No evidence of exploitation in the wild found.
- No public proof of concept found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Google Chrome on all endpoints to 155.0.8059.79 or the current stable release without delay.
- Verify the installed version on all systems, including the Chromium snap on Ubuntu.
- Enforce automatic updates and ensure browsers are restarted after updates.
- Warn users about phishing links and malicious advertisements that lead to unknown web pages.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
