If any mapping was successful before an unsuccessful\nmapping, exactly one DMA mapping (the head) would leak.\n\nThis bug was introduced by a 2010 fix for an endless loop in dma_error.\nAll other affected drivers have already been fixed.","state":0,"publishedAt":"2026-08-15T12:27:23.229+00:00","modifiedAt":"2026-10-16T19:05:50.237+00:00","affected":[{"ecosystem":"Vendor
