In the Linux kernel, the following vulnerability has been resolved: vsock: prevent null-ptr-deref in vsockhasdata|hasspace Recent reports have shown how we sometimes call vsockhasdata when a vsock socket has been de-assigned from a transport see attached links, but we shouldn't. Previous commits...

kernel: vsock/virtio: discard packets if the transport changes

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: discard packets if the transport changes If the socket has been de-assigned or assigned to another transport, we must discard any packets received because they are not expected and would cause issues when we access...

kernel: vsock: Update rx_bytes on read_skb()

A flaw was found in the Linux kernel's vsock component. A local attacker can exploit an imbalance in the rxbytes tracking mechanism, specifically after vsocktransport::readskb fails to update the received bytes count when a packet is dequeued. This can lead to a warning message indicating an empt...
