CVE-2026-31542

CVE-2026-31542 affects the Linux kernel x86/platform/uv component. When a socket is deconfigured, it is mapped to SOCK_EMPTY (0xffff) instead of NUMA_NO_NODE, causing a panic during allocation of UV hub info structures and potentially DoS. The fixes patch the behavior to allocate on valid NUMA no...
