CVE-2024-49856

A flaw was found in the Linux kernel's handling of Intel Software Guard Extensions (SGX) Non-Uniform Memory Access (NUMA) node search. When a system's current NUMA node lacks an Enclave Page Cache (EPC) section configured by firmware, and all other EPC sections are fully utilized, a local user could trigger a condition where the CPU becomes stuck in an indefinite loop. This issue can lead to a soft lockup, resulting in a Denial of Service (DoS) for the affected system.
