Linux of Linux Kernel In NULL Pointer dereference vulnerability
Trust: 0.8
DESCRIPTION
In the Linux kernel, the following vulnerability has been resolved: ipv6: prevent possible NULL dereference in rt6_probe() syzbot caught a NULL dereference in rt6_probe() [1] Bail out if __in6_dev_get() returns NULL.

Linux of Linux Kernel for, NULL There is a vulnerability in pointer dereference.Service operation interruption (DoS) It may be in a state. The RUGGEDCOM RST2428P is a Layer 2 Ethernet switch based on SINEC OS with up to 28 non-blocking interfaces. SCALANCE X switches are used to connect industrial components such as programmable logic controllers (PLCs) and human-machine interfaces (HMIs). Multiple vulnerabilities exist in third-party components prior to SIEMENS SINEC OS V3.2. These vulnerabilities could be exploited to corrupt values, leading to undefined behavior or security issues
