Google Chrome: Memory corruption in Audio allows sandboxed code execution
Summary
Google Chrome versions before 156.0.8078.47 contain a memory corruption flaw in the Audio component. A remote attacker can use a crafted HTML page to execute arbitrary code inside the browser sandbox. The attack requires that a user visits the malicious page, for example via a web link or email link.
Affected
- Google Chrome prior to 156.0.8078.47 (desktop; NVD description)
- Android Chrome builds before 156.0.8078.47 (not verified against Google's Android notice)
- Microsoft Edge and other Chromium-based browsers consume the same fix; HKCERT reports Edge fixed at 156.0.4314.42 or later (not verified against Microsoft)
- Debian chromium packages (DSA 6577-1, DLA 4853-1); Snap-based Chromium must be checked separately
Fixed in
- Chrome 156.0.8078.47 for Linux
- Chrome 156.0.8078.47 or .48 for Windows and macOS
- Stable Channel Update for Desktop, 20 October 2026
Workaround
- None. A patched build exists; no vendor-documented workaround is known.
- Restart the browser after updating, because old browser processes may keep running.
Exploitation
- No evidence of exploitation in the wild in the sources reviewed; CISA KEV status not verified.
- No public proof of concept found; the Chromium bug may be restricted.
- EPSS 0.00417 (third-party aggregator).
Our recommendation
- Update all Chrome installations to 156.0.8078.47 or later (156.0.8078.47/.48 on Windows and macOS) as part of the full Chrome 156 release, which fixes 353 issues.
- Force a browser restart and verify the installed version.
- Check Microsoft Edge, other Chromium-based browsers, and Linux or Snap Chromium builds, as they have separate update cycles.
- Enforce the update in managed fleets and keep an inventory and deployment evidence.
