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 numbuffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting i...

Medium: kernel

Issue Overview: A stack buffer overflow issue was found in the getrawsocket routine of the Host kernel accelerator for virtio net vhost-net driver. It could occur while doing an ictolVHOSTNETSETBACKEND call, and retrieving socket name in a kernel stack variable via getrawsocket. A user able to...

Denial Of Service (DoS)

kvm is vulnerable to denial of service. A flaw was found in the way QEMU-KVM handled erroneous data provided by the Linux virtio-net driver, used by guest operating systems. Due to a deficiency in the TSO TCP segment offloading implementation, a guest's virtio-net driver would transmit improper...
