CVE ID : CVE-2026-19624 CVE-2026-75131 CVE-2026-75883
Andres Berbescu discovered two vulnerabilities in the L2TP connection
plugin for Network Manager which allowed a local user with permissions
to create/activate personal VPN connections to escalate their privileges
to root.
For the stable distribution (trixie), these problems have been fixed in
version 1.20.20-2+deb13u1.
We recommend that you upgrade your network-manager-l2tp packages.
