CVE-2026-102253: Loop with Unreachable Exit Condition

iperf3 versions prior to 3.22 contains a denial of service vulnerability that allows unauthenticated remote attackers to crash-loop the server's UDP receive worker into an unrecoverable infinite loop by sending a single crafted control-channel parameter message followed by one 16-byte UDP datagra...

CVE-2026-102713: Out-of-bounds Read

The TFTP server accepts a DATA datagram of any size. The dispatcher rejects datagrams shorter than four bytes nxdtftpserver.c:1037 and nothing anywhere checks an upper bound, in particular not against the protocol maximum of 4 + NXTFTPFILETRANSFERMAX. Two things follow from that one missing check...
