Description

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