Aug 2026: Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability
CVE-2026-66312 Published on August 3, 2026
Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability
Buffer over-read in Microsoft Edge (Chromium-based) allows an authorized attacker to execute code over a network.
Weakness Type
Buffer Over-read
The software reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer. This typically occurs when the pointer or its index is incremented to a position beyond the bounds of the buffer or when pointer arithmetic results in a position outside of the valid memory location to name a few. This may result in exposure of sensitive information or possibly a crash.
