CVE-2019-9162: High severity Linux Linux kernel vulnerability

Published Feb 25, 2019
·
Updated

In the Linux kernel before 4.20.12, net/ipv4/netfilter/nfnatsnmpbasicmain.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmpversion and snmphelper.
