DescriptionCVE.org

Out of bounds read in Media in Google Chrome on Mac prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Out-of-bounds read in the Media component of Google Chrome on macOS enables sandbox escape for attackers who have already compromised the renderer process. Affected versions are all Chrome for Mac builds prior to 151.0.7922.72; the vendor has released a patched build. No public exploit is identified at time of analysis and EPSS is very low (0.21%, 11th percentile), but the Scope:Changed CVSS metric confirms this crosses Chrome's renderer sandbox boundary - a high-value primitive in multi-stage exploit chains targeting macOS users.

Technical ContextAI

The vulnerability (CWE-125, Out-of-bounds Read) resides in Chrome's Media subsystem, which handles decoding and processing of audio/video content embedded in web pages. Chrome's multi-process security architecture isolates web content in a sandboxed renderer process; a sandbox escape crosses from this constrained environment to the host OS, represented by S:C in the CVSS vector. Affected product CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* with the platform constraint of macOS. The OOB read allows reading memory beyond an allocated buffer boundary, which in a sandbox-escape context is typically used to leak memory layout data enabling further exploitation of the broader OS environment.

RemediationAI

Vendor-released patch: 151.0.7922.72 for macOS. Update Google Chrome to version 151.0.7922.72 or later immediately on all macOS endpoints; Chrome's automatic update mechanism will apply this in most managed environments. The vendor advisory is at http://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. As a compensating control while patching is staged, ensure Chrome's built-in site isolation is active (verify via chrome://flags/#enable-site-per-process) to reduce renderer compromise risk that is a prerequisite for this vulnerability - disabling site isolation would increase exposure to the initial renderer stage. No specific workaround eliminates the OOB read itself without the patch.
