If the server reportsSTATUS_BUFFER_OVERFLOW with OutputCount == 0, SMB2_ioctl() returns-E2BIG with out_data == NULL and out_data_len == 0, and the existinglength checks accept the empty result. The loop then evaluates\n\tnext = out_data[num - 1].file_offset + ...\nwith num == 0, reading 16 bytes before NULL.\nReject a truncated range blob that contains no range, so the resumeoffset is never computed from an empty response. Also require the lastrange in a truncated blob to advance the resume offset withoutoverflowing, and to stay within the requested range; a malicious orbroken server could otherwise make no progress or underflow len and loopforever. Free the previous response buffer before retrying.\nReproduced on 6.6.87.2 with a malicious SMB2 server that answersFSCTL_QUERY_ALLOCATED_RANGES with STATUS_BUFFER_OVERFLOW andOutputCount == 0; an FS_IOC_FIEMAP ioctl on the mount oopses incifs_fiemap() with CR2 = fffffffffffffff8.
