Last modified Jun 17, 2026

CVE-2019-9162 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.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 snmp_version and snmp_helper.. EPSS estimates a 1.09% chance of exploitation in the next 30 days.
