Description
A flaw was found in the Linux kernel's dpaa2-switch component. When an out-of-bounds interface identifier (if_id) is detected in the interrupt handler, the interrupt status is not properly cleared. This oversight can lead to an interrupt storm, resulting in a Denial of Service (DoS) condition for the system.
