Google Chrome: Use after free in Media component
Summary
A use-after-free flaw in the Media component of Google Chrome prior to 156.0.8078.47 allows a remote attacker to execute arbitrary code inside the browser sandbox. Exploitation requires that a user opens a crafted HTML page. Chromium rates the issue Low, and the CVSS score is 8.8. No evidence of exploitation was found, and the impact is limited to the sandboxed renderer unless the flaw is chained with another vulnerability.
Affected
- Google Chrome prior to 156.0.8078.47 (desktop, per CVE description)
- Android Chrome builds prior to 156.0.8078.47 (secondary source)
- Microsoft Edge (Chromium-based) prior to 156.0.4314.42 (HKCERT, not verified against MSRC)
- Debian and Ubuntu: Ubuntu ships Chromium as a snap, so the fix comes via the Chromium snap
Fixed in
- Google Chrome 156.0.8078.47 or later (Linux, Android)
- Google Chrome 156.0.8078.48 or later recommended for Windows and macOS
- Microsoft Edge 156.0.4314.42 or later
- Verify exact versions against the Chrome Releases advisory, which could not be opened directly.
Workaround
Not applicable, since a patch is available. The browser must be fully restarted after the update.
Exploitation
- No evidence of exploitation in the wild found.
- Not listed as known exploited by a third-party tracker; CISA KEV was not checked directly.
- No public proof of concept found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Google Chrome and Microsoft Edge to the fixed versions within the normal browser update cycle.
- Verify the installed version on every endpoint, since a pending update needs a browser restart.
- Check that managed endpoints receive the update through fleet reporting or a policy check.
- Remind users to avoid opening untrusted web pages until the update is applied.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
