Details

In the Linux kernel, the following vulnerability has been resolved:

vsock: Fix sk_error_queue memory leak

Kernel queues MSG_ZEROCOPY completion notifications on the error queue. Where they remain, until explicitly recv()ed. To prevent memory leaks, clean up the queue when the socket is destroyed.
