CVE-2026-85068

Network UPS Tools is a collection of programs which provide a common interface for monitoring and administering UPS, PDU and SCD hardware. From 2.4.2 through 2.8.5, ipponcommand in drivers/blazerusb.c partially initializes char tmp[64] with a short Megatec status query and then passes a fixed eight-byte chunk to usbcontrolmsg. A malicious firmware-controlled USB device presenting the Mustek Powermust VID 0x06da and Mustek Powermust PID 0x0003 matches blazerusbid, selects ipponsubdriver, and can receive the uninitialized trailing stack bytes during normal polling. The disclosure is bounded and read-only, requires physical or supply-chain access to the USB bus, and has no established integrity or availability impact. This issue is scheduled to be fixed in version 2.8.6.
