Use after free in Printing in Google Chrome on Linux 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: Critical)

AnalysisAI

Sandbox escape in Google Chrome on Linux prior to 149.0.7827.53 allows a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a crafted HTML page that triggers a use-after-free in the Printing component. Google rates the underlying Chromium issue as Critical severity, and no public exploit is identified at time of analysis. The CVSS 8.3 score reflects the chained nature of the attack and the scope change that results when sandbox boundaries are crossed.

Technical ContextAI

The bug is a CWE-416 Use-After-Free in Chrome's Printing subsystem, which handles print preview, PDF generation, and the IPC between the renderer and the privileged browser process. Use-after-free conditions occur when a freed memory object is dereferenced again, typically allowing an attacker to control the contents at that address and corrupt program state. Because Printing code runs at least partially in the higher-privileged browser process, a UAF reachable from a compromised renderer becomes a sandbox-escape primitive - the renderer sends crafted printing-related IPC messages or HTML that triggers freed-object reuse in the privileged process, bypassing the site isolation and seccomp/namespace sandbox protections that normally contain a compromised renderer on Linux.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 for Linux - update via the stable channel as described in the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Users of Chromium-based browsers on Linux should apply their vendor's corresponding update once it incorporates this fix. No vendor-supplied workaround is published; as a temporary compensating control, disable Chrome's print preview / printing-from-web functionality via enterprise policy (PrintingEnabled=false) where business-acceptable, which removes user access to print but does not fully neutralize all reachable code paths and breaks any workflow that depends on browser printing. Restricting users to non-Chromium browsers for untrusted browsing is a heavier alternative with obvious usability trade-offs.
