CVE-2026-71401

An integer underflow was found in the DHCPv4 packet capture code of wicked. nicaptureinspectudpheader in src/capture.c does not verify that the IP total length field iplen is at least as large as the IP header length ihl before subtracting the header length. An unauthenticated attacker on the sam...

CVE-2026-71402

An out-of-bounds read was found in the DHCPv4 packet capture code of wicked. nicaptureinspectudpheader in src/capture.c reports the IP total length as the payload length instead of the length of the remaining UDP payload. Consequently, the DHCP option walker in the DHCPv4 client wickedd-dhcp4 rea...

CVE-2026-71402

CVE-2026-71402 is an out-of-bounds read in the DHCPv4 packet capture code of wicked (the openSUSE/SUSE network daemon), specifically in ni_capture_inspect_udp_header() in src/capture.c. The function reports the IP total length as the payload length instead of the remaining UDP payload length, cau...

CVE-2026-71401

An integer underflow in the wicked DHCPv4 packet capture code (function ni_capture_inspect_udp_header() in src/capture.c) allows an unauthenticated attacker on an adjacent network to trigger an out-of-bounds read past the receive buffer in the wickedd-dhcp4 daemon. The IP total length field is no...
