"Google is aware that an exploit for CVE-2026-125350 exists in the wild," the company said in a Monday security advisory. As Google explained, this flaw stems from a Use-After-Free (UAF) weakness in the XML component of the Google Chrome web browser, which occurs when the browser's XML parser processes data, deletes an object from the computer's memory, but fails to clear the pointer referencing that object. Attackers can exploit this high-severity memory corruption vulnerability when the browser later tries to use or read that "freed" memory space to manipulate the memory layout and execute malicious code.
While Google has found evidence of attackers exploiting this zero-day bug in the wild, it has not shared additional details about these incidents. "Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven't yet fixed," it noted.
