A vulnerability in the Linux kernel's Rust IRQ handling was resolved by changing how RegistrationInner is passed as a cookie to request_irq. The issue involved accessing uninitialized memory in the IRQ callback due to the IRQ being enabled before RegistrationInner was fully initialized. This flaw was fixed by ensuring RegistrationInner's fields are initialized before passing it as the IRQ cookie. The vulnerability does not affect mainline Linux kernels where a related commit removed the problematic pattern.
