NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-audio-pa package and not the qemu-audio-pa package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the out_sg variable could be used to read a part of process memory and send it to the wire, causing an information leak.
