  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ndpaa2-switch: Fix interrupt storm after receiving bad if_id in IRQ handler\nCommit 31a7a0bbeb00 (\"dpaa2-switch: add bounds check for if_id in IRQ\nhandler\") introduces a range check for if_id to avoid an out-of-bounds\naccess. If an out-of-bounds if_id is detected, the interrupt status is\nnot cleared. This may result in an interrupt storm.\nClear the interrupt status after detecting an out-of-bounds if_id to avoid\nthe problem.\nFound by an experimental AI code review agent at Google.", "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." ],
