CVE-2026-31542

A flaw was found in the Linux kernel's x86/platform/uv component. When a socket is deconfigured, it is incorrectly mapped to SOCKEMPTY instead of NUMANONODE. This improper handling can lead to a system panic during the allocation of UV hub information structures, resulting in a Denial of Service...
