Google Chrome: Use-after-free in Media component
Summary
Google Chrome desktop versions prior to 155.0.8059.79 contain a use-after-free flaw in the Media component. A remote attacker can exploit it by luring a user to a crafted HTML page, which may allow arbitrary code execution inside the browser sandbox. The victim must visit the page, but no privileges are required. The advisory does not describe a sandbox escape.
Affected
- Google Chrome desktop prior to 155.0.8059.79
- Ubuntu: the chromium-browser package is marked not affected because it installs the Chromium snap
Fixed in
- Google Chrome 155.0.8059.79 or later (Windows and Mac 155.0.8059.79/.80, Linux 155.0.8059.79)
- Debian: 155.0.8059.79-1~deb12u1
- Ubuntu: refresh the Chromium snap
Workaround
Unknown. No workaround is documented; updating is the only mitigation in the sources.
Exploitation
- No evidence of exploitation in the wild found; not verified against the CISA KEV catalogue.
- No public proof of concept found for this CVE.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Chrome to 155.0.8059.79 or later, preferably the current stable build.
- Check the installed version on all endpoints, including Chromium-based browsers and Ubuntu snaps.
- Confirm that automatic updates work and restart browsers so the update takes effect.
- Monitor for news on exploitation and a KEV listing.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
