AI Analysis

Impact

The vulnerability originates from an uninitialized resource within ANGLE, Chrome's OpenGL abstraction layer, a CWE-908 Uninitialized Resource weakness. A maliciously crafted HTML page can trigger the bug, allowing the victim's browser to read data belonging to another origin. The primary impact is the leakage of sensitive information, effectively bypassing same‑origin restrictions.

Affected Systems

Affected systems are Google Chrome browsers with versions earlier than 155.0.8059.39. The patch is included in the stable channel update 155.0.8059.39 and higher.

Risk and Exploitability

The vulnerability is classified as moderate severity (CVSS 4.3), and the vulnerability is known to enable cross‑origin data exfiltration. EPSS data is not available, and the flaw is not listed in the CISA KEV catalog, suggesting no publicly demonstrated exploits at this time. Nonetheless, because the attack can be triggered via a simple web page and requires no privileged conditions, the risk of exploitation in environments where users visit untrusted sites remains moderate to high.
