In the Linux kernel, the following vulnerability has been resolved:
mailbox: zynqmp-ipi: Fix SGI cleanup on unbind
The driver incorrectly determines SGI vs SPI interrupts by checking IRQ
number < 16, which fails with dynamic IRQ allocation. During unbind,
this causes improper SGI cleanup leading to kernel crash.
Add explicit irq_type field to pdata for reliable identification of SGI
interrupts (type-2) and only clean up SGI resources when appropriate.
