Use after free in Audio in Google Chrome on Windows prior to 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome on Windows before 149.0.7827.53 allows a remote attacker who has already compromised the renderer process to break out via a use-after-free in the Audio component when a victim loads a crafted HTML page. Chromium rates the issue High severity and Google has shipped a stable-channel fix, but no public exploit identified at time of analysis and the bug is not listed in CISA KEV.
Technical ContextAI
The flaw is a CWE-416 Use-After-Free in Chromium's Audio subsystem, which on Windows runs in the browser/audio service process outside the renderer sandbox. UAF bugs in this surface typically arise from a media stream object being freed while another code path still holds a dangling pointer, letting an attacker reclaim the freed slot with controlled data and hijack execution. Because the Audio service brokers IPC from sandboxed renderers, a corrupted object there is a classic stepping stone from a renderer compromise to higher-privileged code execution, which is why this class of bug is consistently used as the second link in Chrome exploit chains.
RemediationAI
Vendor-released patch: update Google Chrome on Windows to 149.0.7827.53 or later via the Stable channel auto-update, then force a browser restart so the patched binaries actually load (per https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html). In managed environments, push the update via Chrome Browser Cloud Management or Group Policy and verify deployment with chrome://version; for downstream Chromium browsers, wait for and apply their respective backported builds. If patching must be deferred briefly, compensating controls include disabling the Audio Service via the --disable-features=AudioServiceOutOfProcess flag or AudioSandboxEnabled policy (trade-off: degrades audio reliability and removes a defense-in-depth boundary), and restricting users to known-good sites via SafeSites/URLBlocklist to reduce odds of landing on a chained-exploit page (trade-off: high admin overhead and breaks general browsing).
