qemu < 8.2.0 - Integer Underflow and Buffer Overflow via TI Command in ESP DMA Transfer

Title source: llm
STIX 2.1

Description

QEMU before 8.2.0 has an integer underflow, and resultant buffer overflow, via a TI command when an expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in esp_do_nodma in hw/scsi/esp.c because of an underflow of async_len.
