Buffer overflow via out-of-bounds memory read
Published Oct 15, 2026 · Updated Oct 15, 2026
Out-of-bounds read in HPE NonStop EXPAND T9057L02^AIG and earlier allows attackers to trigger buffer overflow via unspecified vectors. HPE has not disclosed the affected function, triggering input, or how the invalid read produces the overflow. Exploitation requires adjacent-network access without credentials; the specific operational failure is undisclosed.
