CVE-2026-5859

Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 147.0.7727.55

Description An integer overflow exists in the WebML component. This issue allows a remote attacker to potentially cause heap corruption or a denial of service by inducing the browser to process a specially crafted HTML page. Heap corruption occurs when a program mistakenly writes data outside the boundaries of a pre-allocated memory block on the heap, which can lead to arbitrary code execution.

Recommendations Update Google Chrome to version 147.0.7727.55 or later.
