CVE-2026-31542: Linux

Описание

Оригинално описание

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.
