Discussion

Linux Kernel 'dns_key.c' NULL Pointer Dereference Denial of Service Vulnerability

The Linux kernel is prone to a denial-of-service vulnerability in the DNS component.

Attackers can exploit this issue to cause the kernel to dereference an invalid memory location, resulting in a kernel denial-of-service condition.

Linux kernel versions 2.6.37.2 and prior are vulnerable.
