  "description": "In the Linux kernel, the following vulnerability has been resolved:  ata: sata_dwc_460ex: fix infinite loop in NCQ tag completion bit-scanning  The hand-rolled bit-scanning loop in the NCQ completion path has an infinite loop bug.  When tag_mask has only high bits set (e.g. 0x80000000), the inner while loop left-shifts tag_mask until it overflows to 0.  At that point !(0 \u0026 1) is always true and 0 \u003C\u003C= 1 stays 0, causing an infinite loop in hardirq context with a spinlock held.  Replace the open-coded bit-scanning with __ffs() which correctly finds the least significant set bit and is bounded by the width of the argument.",
