CVE-2026-80753

In the Linux kernel, the following vulnerability has been resolved: ovpn: run deferred work on a module-owned workqueue ovpn queues several work items whose callbacks execute module text. These works currently run on the global system workqueues, so module exit has no driver-owned drain point tha...

CVE-2026-80735

In the Linux kernel, the following vulnerability has been resolved: ovpn: ensure socket is owned by ovpn before deref skuserdata Some subsystems, like BPF SOCKMAP, set skuserdata without actually setting the encaptype. For this reason, we must make sure that the type is the one ovpn expects befor...

CVE-2026-80753

CVE-2026-80753 affects the Linux kernel's ovpn module . Work items whose callbacks execute module text ran on the global system workqueues, meaning module exit had no driver-owned drain point to guarantee callbacks had returned before the module text could be freed. Specifically, a worker could d...

In the Linux kernel, the following vulnerability has been resolved: ovpn: ensure socket is owned by ovpn before deref skuserdata Some subsystems, like BPF SOCKMAP, set skuserdata without actually setting the encaptype. For this reason, we must make sure that the type is the one ovpn expects befor...

CVE-2026-80735

CVE-2026-80735 affects the ovpn (OpenVPN) module in the Linux kernel . The root cause is a missing type-check: subsystems such as BPF SOCKMAP can set sk_user_data without setting the expected encap_type, and the ovpn driver dereferences sk_user_data without verifying the socket is actually owned ...

CVE-2026-80735 ovpn: ensure socket is owned by ovpn before deref sk_user_data

In the Linux kernel, the following vulnerability has been resolved: ovpn: ensure socket is owned by ovpn before deref skuserdata Some subsystems, like BPF SOCKMAP, set skuserdata without actually setting the encaptype. For this reason, we must make sure that the type is the one ovpn expects befor...

CVE-2026-80519

A flaw was found in the Linux kernel. Specifically, within the OpenVPN OVPN module's crypto completion callback mechanism, a timing issue exists. This vulnerability arises when peer references are released prematurely, before the associated cleanup operations are complete. An attacker could...

CVE-2026-80520

A flaw was found in the ovpn module of the Linux kernel. The ovpncryptokillkey function incorrectly assumes that both crypto key slots are always populated. This can lead to a NULL dereference if a peer has only one installed key or if the function attempts to remove a key that is not present. A...

CVE-2026-74750

A flaw was found in the Linux kernel's ovpn module. This vulnerability arises from an incorrect handling of cryptographic resource freeing, where a function that requires the ability to pause sleep is executed in a context that does not allow it. This improper resource management could lead to...

EUVD-2026-66580

In the Linux kernel, the following vulnerability has been resolved: ovpn: defer key slot crypto freeing to workqueue Key slots are released through a kref and the existing release path frees the AEAD transforms from an RCU callback. That is not safe for all crypto implementations: cryptofreeaead...

EUVD-2026-66586

In the Linux kernel, the following vulnerability has been resolved: ovpn: fix NULL dereference when killing missing key ovpncryptokillkey assumes both crypto slots are populated and dereferences each slot before checking it. That is not guaranteed: a peer can have only one installed key, and the...

EUVD-2026-66585

In the Linux kernel, the following vulnerability has been resolved: ovpn: finish crypto callback cleanup before peer release Crypto completion callbacks hold both key-slot and peer references. The peer reference pins the netdev, and dropping the last peer reference can let netdev unregistration a...
