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.\n\ud83d\udccf Published: 2024-01-02T09:15:08.280Z\n\ud83d\udccf Modified: 2025-05-06T08:11:12.675Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/errata/RHSA-2024:2962\n2. https://access.redhat.com/errata/RHSA-2025:4492\n3. https://access.redhat.com/security/cve/CVE-2023-6693\n4. https://bugzilla.redhat.com/show_bug.cgi?id=2254580", "creation_timestamp": "2025-05-06T08:20:26.000000Z"}
