CVE-2024-26765

CVE-2024-26765 concerns the Linux kernel on LoongArch. The issue arises when hotplugging nonboot CPUs: IRQs are disabled before calling init_fn(), intended to silence warnings and avoid interrupts, but this is tied to the rcu_cpu_starting warning path (CPU: 1, pid: 0). The result is a race where ...
