CVE-2026-64525
The CVE describes a Linux kernel xfrm policy_bydst RCU synchronization issue where xfrm_policy_fini() called synchronize_rcu() during namespace exit, causing long RCUs and heavy cleanup workload when many namespaces are torn down. The fix moves the policy flush and related workqueue drains into a...

CVE-2026-63919
A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...
CVE-2026-63914
A flaw was found in the Linux kernel's xfrm and afkey modules. The xfrmsendmigrate and pfkeysendmigrate functions incorrectly hardcode the initnet initial network namespace for migration notifications. This misconfiguration leads to two main issues: migration notifications are delivered to the...
CVE-2026-63917
A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...

CVE-2026-63829
A flaw was found in the Linux kernel's IP Generic Routing Encapsulation ipgre component. This vulnerability allows a local attacker with network administration capabilities in one network namespace to modify a tunnel residing in a different network namespace where they lack privileges. This is du...
