CVE-2026-23440

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix race condition during IPSec ESN update In IPSec full offload mode, the device reports an ESN Extended Sequence Number wrap event to the driver. The driver validates this event by querying the IPSec ASO and checking...

PT-2026-30135

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the handling of IPSec ESN Extended Sequence Number wrap events in the mlx5e driver when operating in IPSec full offload mode. After validating an ESN event, th...

The vulnerability of the xfrm_state_delete_tunnel() function in the net/xfrm/xfrm_state.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the xfrmstatedeletetunnel function in the net/xfrm/xfrmstate.c module of the Linux kernel is related to state management errors. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected information...

CVE-2025-40256 xfrm: also call xfrm_state_delete_tunnel at destroy time for states that were never added

In the Linux kernel, the following vulnerability has been resolved: xfrm: also call xfrmstatedeletetunnel at destroy time for states that were never added In commit b441cf3f8c4b "xfrm: delete x-tunnel as we delete x", I missed the case where state creation fails between full initialization...

UBUNTU-CVE-2025-40215

In the Linux kernel, the following vulnerability has been resolved: xfrm: delete x-tunnel as we delete x The ipcomp fallback tunnels currently get deleted from the various lists and hashtables as the last user state that needed that fallback is destroyed not deleted. If a reference to that user...

CVE-2025-38675

In the Linux kernel, the following vulnerability has been resolved: xfrm: state: initialize stateptrs earlier in xfrmstatefind In case of preemption, xfrmstatelookat will find a different pcpuid and look up states for that other CPU. If we matched a state for CPU2 in the statecache while the look...

CVE-2025-38675

The CVE describes a Linux kernel xfrm_state_find/ look_at race where, on preemption across CPUs, a cached state for one CPU can be ignored and an uninitialized state_ptrs is used in the acquire path. The fix initializes state_ptrs immediately after taking rcu_read_lock to prevent this misuse. Imp...

CVE-2025-38590

CVE-2025-38590: In the Linux kernel mlx5e IPsec offload path, if the decrypted xfrm state is not found, the secpath on the skb may remain and be dereferenced by __xfrm_policy_check(), causing a crash. The documented fix explicitly removes the skb secpath when the xfrm state lookup fails after har...
