OPENSUSE-SU-2026:21669-1 Security update for wicked

This update for wicked fixes the following issues: Changes in wicked: - Fix two OOB reads in nicaptureinspectudpheader and improve: - Reject packets with iplen ihl to avoid a sizet underflow of the UDP length, which the checksum truncates to uint16t bsc1274627, CVE-2026-71401. - Set payloadlen to...

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...

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...

USN-8686-1: openCryptoki vulnerabilities

It was discovered that primitive decoders in openCryptoki produced integer underflows when the encoded length was zero. An attacker could possibly use this issue to trigger out-of-bounds reads. CVE-2026-40253 It was discovered that openCryptoki incorrectly handled symlinks. An attacker in the...

CVE-2026-80584

A flaw was found in the Linux kernel's s390/qeth component. This vulnerability allows a local attacker to trigger an integer underflow when handling user-supplied buffer lengths in the qethsnmpcommand and qethl3arpquery functions. This can lead to an out-of-bounds write, potentially causing memor...

CVE-2026-74754

A flaw was found in the Linux kernel SCSI core. A race condition exists where the shost-ehnoresume flag is checked multiple times during error handling. This can lead to an incorrect handling of power management PM references, specifically an unmatched reference put. The consequence is a runtime ...
