Google Chrome: Use-after-free in WebGL allows code execution in sandbox
Summary
A use-after-free flaw in the WebGL component of Google Chrome on Android allows a remote attacker to execute arbitrary code inside the browser sandbox. The attack requires that a user opens a crafted HTML page. Code execution inside the sandbox is not a full browser escape, and no sandbox escape has been reported in the sources reviewed.
Affected
- Google Chrome on Android prior to 156.0.8078.47
- Desktop exposure is unclear because the CVE text names only Android; check the Chrome Releases post.
- Chromium-based browsers, such as Microsoft Edge, may consume the upstream fix; check their vendor advisories.
Fixed in
- Google Chrome for Android: 156.0.8078.47 or later
- Desktop and Linux distributions: unknown in the primary sources; check the Chrome Releases post and your distribution's advisory.
Workaround
Unknown.
Exploitation
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.
- No evidence of active exploitation was found in the sources reviewed.
Our recommendation
- Update Google Chrome on Android to 156.0.8078.47 or later.
- Check desktop Chrome and other Chromium-based browsers in your environment and update them according to the vendor advisories.
- On Ubuntu, update the Chromium snap, since the chromium-browser package only installs the snap.
- Restrict browsing of untrusted HTML content on managed devices where possible.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
