CVE-2022-50093

CVE-2022-50093 affects the Linux kernel IOMMU VT-d code. The issue arises from using arch_test_bit() with a possibly invalid first argument when NUMA is disabled, causing a potential wild memory access after node_online() returns NUMA_NO_NODE. The fix adds an explicit check for node != NUMA_NO_NO...
