CVE-2024-24474

Qemu buffer overflow

8.8 HIGHPublic exploitEPSS 1.40%
  1. Published20 Feb 2024

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.
