CVE-2022-24808Network attack vector

Authenticated service crash via unchecked table indexes

Published Apr 16, 2024 · Updated Aug 3, 2024

NULL pointer dereference in Net-SNMP before 5.9.2 allows remote authenticated users to crash snmpd with a malformed nsLogTable SET request. handle_nsLoggingTable extracts table metadata and dereferences its index list without first ensuring that the malformed request supplied either value. Read-write SNMP credentials and network access to the agent are required; successful exploitation interrupts the SNMP service without reported data exposure.
