Analysis

Impact

A use‑after‑free flaw in Chrome for iOS prior to version 150.0.7871.47 permits a remote attacker to provoke heap corruption by serving a specially crafted HTML page. This memory safety error is classified as CWE‑416 and is evaluated with CVSS score of 8.8, indicating a high‑severity vulnerability.

Affected Systems

All users running Google Chrome on iOS devices with a browser version earlier than 150.0.7871.47 face the risk. The flaw resides in the rendering engine that processes HTML content and can be triggered by remote content.

Risk and Exploitability

The flaw can be triggered when a victim’s device renders a crafted HTML page delivered from a remote attacker, possibly leading to heap corruption or more advanced exploitation. The EPSS score is < 1 %, indicating a very low but non‑zero exploitation probability, and the vulnerability is not listed in the CISA KEV catalog. The CVSS score of 8.8 indicates a high‑severity vulnerability.
