However, Sashiko\nreports that the mp2975 driver already supports up to 14 phases, and the\nmp2856 driver supports up to 12 phases. This already has the potential for\nout-of-bounds writes when probing the affected chips, making this patch a\nbug fix.","state":0,"publishedAt":"2026-10-06T08:44:37.623+00:00","modifiedAt":"2026-10-19T09:15:30.3+00:00","affected":[{"ecosystem":"Vendor
