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.

Affected products

• QEMU: before 8.2.0 — fixed in 8.2.0

How to fix

Upgrade to a fixed version: QEMU 8.2.0. Check the vendor advisory for mitigations.
