AI Analysis

Impact

The vulnerability is a classic use‑after‑free that occurs within Chrome’s USB handling code on macOS. When a renderer process that has already been compromised processes a specially crafted HTML page, the code dereferences memory that has already been freed, allowing arbitrary code to be executed. This misuse of memory aligns with CWE‑416 and can potentially break out of the Chrome sandbox, giving the attacker privileges equivalent to the Chrome process on macOS.

Affected Systems

Google Chrome on macOS running any stable desktop channel release prior to 150.0.7871.47. The issue is confined to those older releases; later Chrome versions contain a patch that eliminates the use‑after‑free.

Risk and Exploitability

The defect is rated as high severity with a CVSS score of 9.6. The EPSS score of less than 1 percent indicates a low likelihood of exploitation, and the vulnerability is not listed in CISA’s KEV catalog. An attacker would need to supply a malicious HTML payload that is processed by a compromised renderer process; once the use‑after‑free is triggered, the attacker can escape the sandbox and execute code with the Chrome process’s privileges.
