The length of the response is\nrecorded in rsp_iov.iov_len, but nothing constrains it to be at least\nread_rsp_size before those fields are dereferenced.\n\nA malicious or compromised SMB1 server can return a response shorter\nthan the READ_RSP header, so that parsing the header itself reads past\nthe end of the receive buffer. SMB1 is not negotiated by default;\nreaching this code requires an explicit vers=1.0 mount.\n\nReject the response unless it is at least read_rsp_size bytes long.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
