Google Chrome: Buffer overflow in Animation allows code execution in sandbox
Summary
Google Chrome before 155.0.8059.79 contains a heap-based buffer overflow in its Animation component (CWE-122). A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The CVE record does not describe a sandbox escape, and Chromium rates the issue High.
Affected
- Google Chrome before 155.0.8059.79
- Other Chromium-based browsers must be checked separately for their own fixed builds.
Fixed in
- Google Chrome 155.0.8059.79 or later (Debian package data lists 155.0.8059.79-1~deb12u1 for bookworm)
- Newer stable builds of Chrome are available and should be used.
Workaround
Unknown. No vendor workaround is known. Updating Chrome is the practical mitigation.
Exploitation
- Not listed in CISA KEV according to one aggregator (not verified against the catalogue).
- No confirmed public proof of concept (low-confidence source).
- Exploitation in the wild: Unknown.
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Google Chrome to the current stable release on all endpoints.
- Check Microsoft Edge and other Chromium-based browsers for available updates.
- Verify that managed devices apply the Chrome update policy and that browsers have been restarted after updating.
- Monitor for reports of active exploitation.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
