  "details": "In the Linux kernel, the following vulnerability has been resolved:  cxl/features: Reject Get Feature count larger than the output buffer  cxlctl_get_feature() sizes its output buffer from the user's fwctl_rpc.out_len, but the device is told to write cxl_mbox_get_feat_in.count bytes into rpc_out-\u003epayload, which is a separate user-controlled value. Nothing bounds count against out_len, so a small out_len with a large count overflows the kvzalloc()'d buffer. A heap OOB write reachable from FWCTL_RPC.  Reject requests where count exceeds the available payload room, before allocating.",
