kernel: vsock: Keep the binding until socket destruction

A flaw was found in the Linux kernel's virtual socket protocol network driver, where an improperly timed socket unbinding could result in a use-after-free issue. This flaw allows an attacker who can create and destroy arbitrary connections on virtual connections to read or modify system memory,...

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...
