CVE-2026-68432

A flaw was found in the Linux kernel's VXLAN Virtual Extensible LAN implementation. A local attacker, with CAPNETADMIN network administration capability in one network namespace, could exploit an incorrect privilege check in the rtnl changelink path. This allows the attacker to modify the...

CVE-2026-68142

A flaw was found in the geneve component of the Linux kernel. A local attacker, with CAPNETADMIN privileges in a specific network namespace, could bypass intended permission checks. This allows them to modify the configuration of a geneve network device in a different network namespace, potential...

CVE-2026-68294

A flaw was found in the Linux kernel's QRTR Qualcomm IPC Router networking component. An unprivileged local attacker can create a QRTR socket in a separate network namespace. Due to improper handling of global state variables, this allows the attacker to send datagrams and control-plane messages ...

CVE-2026-68335

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS component. The RDS component incorrectly handles incoming messages that cross network namespace boundaries, allowing a sender in one network namespace to deliver a message to a socket in a different network namespace. This can...

CVE-2026-68290

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS TCP implementation. A race condition can occur during network namespace teardown, where a concurrent system control sysctl write operation attempts to access a socket that has already been freed. This use-after-free vulnerabilit...
