CVE-2026-71402

A flaw was found in wicked. An unauthenticated attacker on the same network who sends a crafted DHCP/UDP packet can trigger an out-of-bounds read vulnerability in the DHCPv4 option parser. This allows the client to parse adjacent heap memory as DHCP options, potentially leading to the disclosure ...

CVE-2026-71401

A flaw was found in wicked, specifically in its DHCPv4 packet capture code. An integer underflow vulnerability exists where the nicaptureinspectudpheader function fails to validate the IP total length field against the IP header length before performing a subtraction. This oversight allows an...

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...
