SUSE CVE-2026-72256

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtcluster: reject template conntracks in hash match xtclustermt treats any non-NULL nfctget result as a fully initialized conntrack and passes it to xtclusterhash. This causes a state confusion bug when the raw table C...

CVE-2026-80585

A flaw was found in the Linux kernel. In the Multipath TCP MPTCP Fast Open feature, a vulnerability exists where the system incorrectly marks a subflow as MPTFO even when a TCP Fast Open TFO SYN packet does not contain data. This can lead to a stale MPTFO state, potentially triggering a...
