Feb 2026: GDI+ Denial of Service Vulnerability
CVE-2026-20846 Published on February 10, 2026
Buffer over-read in Windows GDI+ allows an unauthorized attacker to deny service 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.
