Analysis

Impact

A use‑after‑free flaw exists in Chrome’s SignIn component. The vulnerability can be triggered when a user visits a specially crafted HTML page and performs the required UI gestures, leading to heap corruption. The resulting memory corruption can potentially enable arbitrary code execution or cause the browser to crash, compromising both confidentiality and integrity of the system.

Affected Systems

Google Chrome versions prior to 150.0.7871.47 are affected. This includes all desktop builds of Chrome that have not yet been upgraded to the released security update.

Risk and Exploitability

The CVSS score of 8.8 indicates high severity, but the EPSS score of less than 1 % and the fact that the vulnerability is not listed in the CISA KEV catalog suggest that exploitation is expected to be low. Attacking requires the victim to open the malicious page and complete the UI gestures, meaning the attack is not easily automated and relies on user interaction. Nonetheless, once triggered the impact could be severe, making the issue noteworthy.

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