In the Linux kernel, the following vulnerability has been resolved: virtio-net: xsk: rx: fix the frame's length check When calling buftoxdp, the len argument is the frame data's length without virtio header's length vi-hdrlen. We check that len with xskpoolgetrxframesize + vi-hdrlen to ensure the...

kernel: vsock: Fix sk_error_queue memory leak

A flaw was found in the Linux kernel's Virtual Socket vsock implementation. When zero-copy data transfers are used, completion notifications placed on a socket's error queue are not cleared when the socket is closed. A local user can exploit this flaw to trigger an uncollected memory leak,...
