CVE-2024-27030: octeontx2-af: Use separate handlers for interrupts
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Use separate handlers for interrupts
For PF to AF interrupt vector and VF to AF vector same interrupt handler is registered which is causing race condition. When two interrupts are raised to two CPUs at same time then two cores serve same event corrupting the data.
