Analysis

Impact

A use‑after‑free flaw exists in Chrome’s Bluetooth handling on macOS. A remote attacker who has already compromised the renderer process can trigger the defect by serving a crafted HTML page, causing the renderer to access freed memory and potentially escape its sandbox. The flaw is classified as CWE‑416, and Chromium rates it as medium severity.

Affected Systems

Google Chrome on macOS versions prior to 150.0.7871.47 with Bluetooth enabled is vulnerable. Any installation where Bluetooth is implemented within the browser is impacted until the product is upgraded to the patched release.

Risk and Exploitability

The vulnerability carries a CVSS score of 9.6, indicating high severity. The EPSS score is less than 1%, suggesting a very low likelihood of exploitation at present. The flaw is not listed in the CISA KEV catalog. Exploitation requires the attacker to already have compromised the renderer process and trigger the use‑after‑free through a crafted HTML page, potentially leading to a sandbox escape.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
