Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: unbound (UTSA-2026-123924)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-123924 advisory. In NLnet Labs Unbound 1.4.22 up to and including 1.25.1, UDP source port is randomized and intended to serve as a secret value that increases the entropy of DNS...

unbound: Unbound: DNS cache poisoning via UDP source port predictability

A flaw in Unbound's SOREUSEPORT implementation reduces UDP source port entropy by allowing attackers to map ports to specific worker threads. This enables DNS cache poisoning, potentially leading to traffic redirection or unauthorized information disclosure...

kernel: tcp: call sk_data_ready() after listener migration

A flaw was found in the Linux kernel's TCP networking subsystem. When an established network connection is migrated between listener sockets within the same SOREUSEPORT group, applications waiting for new connections may not be properly notified. This can cause poll, epollwait, and blocking accep...

SUSE CVE-2026-74696

In the Linux kernel, the following vulnerability has been resolved: tcp: fix TFO maxqlen accounting across reuseport migration A listener's TCPFASTOPEN maxqlen stops being accurate and lets through far more pending Fast Open requests than it was configured for. This only shows up with SOREUSEPORT...

CVE-2026-74696

A flaw was found in the Linux kernel's TCP Fast Open TFO implementation. During SOREUSEPORT listener migration, the system incorrectly accounts for pending TCP Fast Open requests. This can lead to a Denial of Service DoS by allowing an excessive number of Fast Open requests, potentially exhaustin...
