Doc Text:
A flaw was found in chromium-browser. An uninitialized resource in the Graphics Processing Unit (GPU) component can lead to information disclosure by allowing memory to be read from outside the security sandbox. A remote attacker who has already compromised the browser's renderer process could exploit this flaw by enticing a user to view a crafted web page, enabling them to bypass process isolation boundaries and access unauthorized data.
