Stack-based buffer overflow in ELAN Smart-Pad Windows kernel drivers ETD.sys and ETDSMBus.sys allows a local standard-privilege user to crash the entire Windows system via a kernel bugcheck (BSOD 0xF7 DRIVER_OVERRAN_STACK_BUFFER). The vulnerability is rooted in the Intel SMBus recovery code path: ETDSMBus.sys accepts a hardware-derived report count without enforcing an upper bound and forwards it to ETD.sys, where it drives an unbounded stack buffer copy. A proof-of-concept exists (CVSS 4.0 E:P) and no confirmed patch version has been identified from available data; no active exploitation is listed in CISA KEV at time of analysis.
