CVSS 6.300000190734863 MEDIUM
A flaw was found in the Linux kernel's Asynchronous Transfer Mode (ATM) networking component. A local attacker, by acting as a malicious signaling daemon, could send a specially crafted message containing an unvalidated pointer. This unvalidated pointer would be directly used by the kernel, leading to the dereference of an arbitrary memory address. The consequence is a system crash, resulting in a Denial of Service (DoS).
