Firmware buffer overflow via incorrect authorization
Published May 4, 2026 · Updated May 4, 2026
Buffer overflow in Qualcomm Snapdragon QCA7005 PLC firmware allows attackers to corrupt memory through an incorrect authorization check. Qualcomm has not disclosed the affected handler, the input that reaches it, or the specific operation that overruns the buffer. Exploitation requires adjacent-network reachability but no privileges or user interaction; the vendor has not published a consequence beyond the buffer overflow.
