CVE-2024-53075

The CVE-2024-53075 entry concerns the Linux kernel riscv path used while populating cache leaves. Root cause: when ACPI is enabled, the code path early-returns and omits of_node_put for the CPU device node, creating a potential bad reference count. The fix moves the CPU node initialization to aft...
