Title: Linux Kernel ULE Packet Handling Remote Denial of Service Vulnerability
Severity: MODERATE
Description:
The Linux kernel is prone to a remote denial-of-service vulnerability.
This issue is triggered when the kernel handles a specially crafted Unidirectional Lightweight Encapsulation (ULE) packet. Specifically, a packet containing an SNDU length value of 0 can cause the kernel to crash.
This issue allows remote attackers to trigger a denial of service for legitimate users.
Kernel version 2.6.17.8 is reported vulnerable; other versions may be affected as well.
