The vulnerability of the L2ALM component in Juniper Networks’ Junos OS-based QFX router series allows a hacker to induce a service failure.

The vulnerability of the L2ALM component Layer 2 Address Learning Manager in Juniper Networks’ Junos OS-based QFX series routers stems from the use of memory after it is freed due to synchronization errors when using shared resources. Exploiting this vulnerability can allow a malicious actor to...

kernel: l2tp: close all race conditions in l2tp_tunnel_register()

In the Linux kernel, the following vulnerability has been resolved: l2tp: close all race conditions in l2tptunnelregister The code in l2tptunnelregister is racy in several ways: 1. It modifies the tunnel socket after publishing it. 2. It calls setupudptunnelsock on an existing socket without...

kernel: l2tp: missing lock when clearing sk_user_data can lead to NULL pointer dereference

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol L2TP. A missing lock when clearing skuserdata can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service...
