A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to some errors within the "snmp_trap_decode()" function when handling certain SNMP packets. This can be exploited to cause memory corruption due to incorrect freeing of memory, which can potentially cause the system to crash.
Successful exploitation requires that the "ip_nat_snmp_basic" module is loaded and that traffic NAT is enabled on port 161 or 162.
Provided and/or discovered by: Reported by the vendor.
