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