CVE-2023-6693

一、漏洞信息
漏洞编号：CVE-2023-6693
漏洞归属组件：qemu
漏洞归属的版本：4.1.0,5.2.0,6.2.0,7.2.0
CVSS V3.0分值：
BaseScore：5.3 Medium
Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
漏洞简述：
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.
