  "description": "In the Linux kernel, the following vulnerability has been resolved:  cxl/features: Reject Set Features output buffer smaller than the header  cxlctl_set_feature() sizes its output buffer from the user\u0027s fwctl_rpc.out_len but never checks it is large enough to hold even the fwctl_rpc_cxl_out header. With out_len == 0 , kvzalloc() returns ZERO_SIZE_PTR, which passes the !rpc_out check, the subsequent rpc_out-\u003Esize = 0 then writes through the poison pointer.  Reject requests whose output buffer can\u0027t hold the response header, before allocating. The Set Feature reply carries no payload, so the header is all that is required.",
