Use After Free in Printing in Google Chrome on Linux, Mac, ChromeOS prior to 148.0.7778.96 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Sandbox escape in Google Chrome prior to 148.0.7778.96 on Linux, Mac, and ChromeOS allows remote attackers who have already compromised the renderer process to break out of Chrome's sandbox via a crafted HTML page exploiting a use-after-free vulnerability in the printing subsystem. Despite the 8.3 CVSS score, Chromium rates this Low severity because exploitation requires a two-stage attack chain (initial renderer compromise followed by sandbox escape). Vendor patch released as Chrome 148.0.7778.96. No evidence of active exploitation or public POC identified at time of analysis.

Technical ContextAI

The vulnerability is a use-after-free (CWE-416) memory corruption flaw in Chrome's printing implementation, affecting the Linux, macOS, and ChromeOS builds. Use-after-free vulnerabilities occur when code continues to use a memory pointer after the memory has been freed, allowing attackers to manipulate heap memory structures. In Chrome's multi-process architecture, renderer processes handle untrusted web content in a restricted sandbox, while privileged browser processes operate outside the sandbox. This flaw specifically enables sandbox escape - a critical security boundary breach that converts a contained renderer exploit into full system compromise. The printing subsystem likely triggers the freed memory reference during document rendering or print preview operations, creating an exploitable window for heap manipulation.

RemediationAI

Update Google Chrome to version 148.0.7778.96 or later, available through Chrome's automatic update mechanism (chrome://settings/help) or direct download from google.com/chrome. The vendor-released patch addresses the use-after-free in the printing subsystem. Chrome's automatic update system typically deploys patches within 24-48 hours for most users. Full advisory details available at chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html. No workaround is documented because the flaw resides in core browser functionality. Organizations unable to patch immediately should consider compensating controls: deploy browser isolation technologies that contain exploits even after sandbox escape, restrict Chrome usage to trusted sites via allowlisting policies, or enforce Chromium-based alternatives already at version 148.0.7778.96+. Note that disabling printing functionality is not a viable mitigation as Chrome does not expose granular feature controls for the affected subsystem, and blocking print operations would severely impact user workflows.
