kernel: race condition in net/can/bcm.c leads to local privilege escalation

A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges...

Smurf DDoS attack:❗️ How it works and how to mitigate

Attacks geared at denying users access to servers are executed in different ways. One notable approach — similar in many forms of service denials — is the use of volume. The sheer volume of requests is employed by attackers to render a particular network useless. A good representation of that is...
