Description

The Linux kernel contains a flaw that may allow a remote denial of service. The issue is triggered when the 'ip_nat_snmp_basic' module is loaded and NAT is performed on ports 161 or 162. The 'snmp_trap_decode()' function is the cause for potential multiple freeing of memory, which will result in memory corruption and hence loss of availability for the platform.
