Security update for wicked
This update for wicked fixes the following issues: Changes in wicked: - Fix two OOB reads in ni_capture_inspect_udp_header and improve: - Reject packets with ip_len < ihl to avoid a size_t underflow of the UDP length, which the checksum truncates to uint16_t (bsc#1274627, CVE-2026-71401). - Set payload_len to the remaining payload, not ip_len, which over-read the DHCP option walker by ihl + 8 bytes past the buffer (bsc#1274627, CVE-2026-71402). - Avoid checksumming packets that fail the length/protocol checks and tidy up the debug messages (bsc#1274627). - Fix underflow check in ni_dhcp4_option_next to handle option code and length separately as the END and PAD options don't have length (bsc#1274627). Thanks to Daniel Birtwhistle for discovering and reporting the issues.
