Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
x86/platform/uv: Handle deconfigured sockets
When a socket is deconfigured, it's mapped to SOCK_EMPTY (0xffff). This causes
a panic while allocating UV hub info structures.
Fix this by using NUMA_NO_NODE, allowing UV hub info structures to be
allocated on valid nodes.
