Astra Linux – Vulnerability in Qemu

QEMU prior to version 8.2.0 has an integer underflow issue, which can lead to a buffer overflow. This occurs due to a TI command, where a transfer length that is not a DMA transfer is processed, even though that length is shorter than the length of the available FIFO data. This issue arises in th...
