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.

No CVSS v4.0

No CVSS v3.1
