GHSA-PFXG-46GM-P35H

Vulnerability from github – Published: 2024-11-14 12:31 – Updated: 2024-11-14 12:31

Details

A heap buffer overflow was found in the virtio-snd device in QEMU. When reading input audio in the virtio-snd input callback, virtio_snd_pcm_in_cb, the function did not check whether the iov can fit the data buffer. This issue can trigger an out-of-bounds write if the size of the virtio queue element is equal to virtio_snd_pcm_status, which makes the available space for audio data zero.

Severity ?

7.4 (High)
