Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A flaw was discovered in the Linux kernel’s Layer 2 Tunneling Protocol L2TP. Clearing the skuserdata can result in a race condition and NULL pointer dereferencing. A local user could exploit this flaw to potentially crash the system, causing a denial of service...

SUSE 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-2026-80735

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 ...
