https://notcve.org/view.php?id=CVE-2021-3748
A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process. Se ha encontrado una vulnerabilidad de uso de memoria previamente liberada en el dispositivo virtio-net de QEMU. Podría ocurrir cuando la dirección del descriptor pertenece a la región de acceso no directo, debido a que num_buffers es establecido después de que el elemento virtqueue haya sido desmapeado. • https://bugzilla.redhat.com/show_bug.cgi?id=1998514 https://github.com/qemu/qemu/commit/bedd7e93d01961fcb16a97ae45d93acf357e11f6 https://lists.debian.org/debian-lts-announce/2022/04/msg00002.html https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html https://lists.nongnu.org/archive/html/qemu-devel/2021-09/msg00388.html https://security.gentoo.org/glsa/202208-27 https://security.netapp.com/advisory/ntap-20220425-0004 https://ubuntu.com/security/CVE-2021-3748 https://access. • CWE-416: Use After Free •
