Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

media: venus: protect against spurious interrupts during probe

Make sure the interrupt handler is initialized before the interrupt is registered.

If the IRQ is registered before hfi_create(), it’s possible that an interrupt fires before the handler setup is complete, leading to a NULL dereference.

This error condition has been observed during system boot on Rb3Gen2.
