IBM VMI Crash via Auth Admin (FW1110-1110.30, FW1120.00, FW1060-1060.80)
CVE-2026-16724 Published on August 19, 2026
Power System Integer Overflow
IBM Virtualization Management Interface FW1110.00 through FW1110.30, FW1120.00 through FW1120.00, and FW1060.00 through FW1060.80 is affected by a vulnerability in the Virtualization Management Interface (VMI). An attacker with authenticated administrator-level access can cause the VMI to crash. The VMI will restart automatically; however, repeated exploitation could result in a sustained availability impact.
Vulnerability Analysis
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.
