Oct 2026: Windows Kernel-Mode Driver Elevation of Privilege Vulnerability
CVE-2026-83573 Published on October 13, 2026
Windows Kernel-Mode Driver Elevation of Privilege Vulnerability
Integer overflow or wraparound in Windows Kernel Mode Driver allows an unauthorized attacker to elevate privileges with a physical attack.
Weakness Type
Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.
