DescriptionCVE.org

Use after free in Skia in Google Chrome 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: High)

AnalysisAI

Sandbox escape in Google Chrome versions prior to 148.0.7778.96 allows remote attackers who have already compromised the renderer process to break out of Chrome's security sandbox through a use-after-free vulnerability in the Skia graphics library. Exploitation requires user interaction with a malicious HTML page and successful prior renderer compromise, representing a second-stage attack rather than initial access. No active exploitation confirmed (not in CISA KEV), though the vulnerability's sandbox escape capability makes it valuable for targeted attack chains.

Technical ContextAI

Skia is Chrome's 2D graphics rendering engine responsible for drawing web page elements, canvas operations, and UI components. The CWE-416 use-after-free occurs when code attempts to access memory after it has been freed, typically due to incorrect object lifetime management or race conditions during asynchronous operations. In Skia's context, this often involves graphics object destruction while references remain active during rendering operations. The CVSS scope change (S:C) reflects the vulnerability's ability to escape Chrome's multi-process sandbox architecture, where renderer processes normally operate with restricted privileges isolated from the underlying operating system. The 'High' Chromium security severity reflects the sandbox escape capability, as renderer compromise alone is typically rated lower without the privilege escalation component.

RemediationAI

Update Google Chrome to version 148.0.7778.96 or later immediately via the built-in auto-update mechanism (Settings → About Chrome) or by downloading from https://www.google.com/chrome/. The vendor-released patch is confirmed available per the stable channel update announcement at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html. Chrome typically auto-updates within 24-48 hours of release, but manual update verification is recommended for enterprise environments. For organizations unable to patch immediately, compensating controls include: restricting Chrome usage to trusted sites only via enterprise policy URL allowlists (ChromeEnterpriseAllowlist), though this significantly limits browser functionality and user productivity; deploying browser isolation solutions that render untrusted content in remote containers, adding another sandbox layer but introducing latency and infrastructure costs; or temporarily switching to alternative browsers until patching is complete, which may disrupt workflows dependent on Chrome-specific features or extensions. None of these workarounds provide complete protection since the vulnerability exists in the installed Chrome binary.
