Out of bounds read and write in Media in Google Chrome on Mac prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox-confined arbitrary code execution in Google Chrome on macOS versions prior to 149.0.7827.103 stems from an out-of-bounds read and write in the Media component, exploitable by a remote attacker who has already compromised the renderer process and lures a user to a crafted HTML page. Google rates the Chromium severity as High and has released a patched stable channel update; no public exploit identified at time of analysis, and SSVC reports no observed exploitation.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have already compromised the Chrome renderer process on macOS (an explicit precondition in Google's description), the victim must be running a vulnerable Chrome build below 149.0.7827.103 on macOS specifically, and user interaction is needed to load a crafted HTML page containing the malicious media payload. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.5 (High) with vector AV:N/AC:H/PR:N/UI:R reflects meaningful real-world friction: the attack is network-reachable but requires high complexity, user interaction (visiting a crafted page), and - critically per the description - prior compromise of the renderer process, which the CVSS PR:N field arguably understates. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already chained an initial renderer-process compromise (for example via a separate JavaScript engine bug) directs the victim browser to a crafted HTML page containing malicious media content that triggers the out-of-bounds read/write in the Media component, achieving arbitrary code execution within the sandboxed renderer. This bug would typically be paired with a sandbox escape to fully exfiltrate data or pivot onto the host. … |
| Remediation | Vendor-released patch: Google Chrome 149.0.7827.103 for macOS - update via the stable channel as documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html, then restart the browser to activate the new build. … Detailed patch versions, workarounds, and compensating controls in full report. |
