In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: Fix interrupt storm after receiving bad if_id in IRQ handler Commit 31a7a0bbeb00 ("dpaa2-switch: add bounds check for if_id in IRQ handler") introduces a range check for if_id to avoid an out-of-bounds access. If an out-of-bounds if_id is detected, the interrupt status is not cleared. This may result in an interrupt storm. Clear the interrupt status after detecting an out-of-bounds if_id to avoid the problem. Found by an experimental AI code review agent at Google.
