Medium CVSS 5.3
Summary
The Espressif ESP-hosted Wi-Fi driver (drivers/wifi/esp_hosted/) parses frames received over SPI from the ESP co-processor in esp_hosted_event_task(). For control frames it took the 16-bit TLV field data_length straight off the wire and passed it to pb_istream_from_buffer(frame.data_value, frame.data_length) without checking it against the frame length or the receive buffer. frame.data_value sits 26 bytes into a 3188-byte stack object, so a data_length of up to 0xFFFF makes pb_decode() read up …
