Ubuntu.comUB:CVE-2024-42140CVE-2024-42140
In the Linux kernel, the following vulnerability has been resolved:
riscv: kexec: Avoid deadlock in kexec crash path
If the kexec crash code is called in the interrupt context, the
machine_kexec_mask_interrupts() function will trigger a deadlock while
trying to acquire the irqdesc spinlock and then deactivate irqchip in
irq_set_irqchip_state() function.
Unlike arm64, riscv only requires irq_eoi handler to complete EOI and
keeping irq_set_irqchip_state() will only leave this possible deadlock
without any use. So we simply remove it.
