Descriptions

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.

QEMU anterior a 8.2.0 tiene un desbordamiento de número entero y un desbordamiento de búfer resultante, a través de un comando TI cuando una longitud de transferencia esperada que no es DMA es menor que la longitud de los datos FIFO disponibles. Esto ocurre en esp_do_nodma en hw/scsi/esp.c debido a un desbordamiento insuficiente de async_len.

Markus Frank and Fiona Ebner discovered that QEMU did not properly handle certain memory operations, leading to a NULL pointer dereference. An authenticated user could potentially use this issue to cause a denial of service. Xiao Lei discovered that QEMU did not properly handle certain memory operations when specific features were enabled, which could lead to a stack overflow. An attacker could potentially use this issue to leak sensitive information.
