kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

CVE-2025-38097: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: espintcp: remove encap socket caching to avoid reference leak The current scheme for caching the encap socket can lead to reference leaks when we try to delete the netns. The reference chain is: xfrmstate - enacpsk - netns Since...

CVE-2025-21864

In the Linux kernel, the following vulnerability has been resolved: tcp: drop secpath at the same time as we currently drop dst Xiumei reported hitting the WARN in xfrm6tunnelnetexit while running tests that boil down to: - create a pair of netns - run a basic TCP test over ipcomp6 - delete the...

CVE-2025-21864

CVE-2025-21864 affects the Linux kernel TCP path. The issue arises when netns are deleted and an skb defers free, leaving a lingering reference to an xfrm_state via the secpath attached to the skb. The kernel previously dropped dst but not the secpath; the fix drops the secpath in the TCP receive...
