This issue affects the function SNMP-VIEW-BASED-ACM-MIB::vacmAccessTable of the component OID Handler. The manipulation with an unknown input leads to a improper protection for out of bounds signal level alerts vulnerability. Using CWE to declare the problem leads to CWE-1320. Untrusted agents can disable alerts about signal conditions exceeding limits or the response mechanism that handles such alerts. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a malformed OID in a SET request to `SNMP-VIEW-BASED-ACM-MIB::vacmAccessTable` can cause an out-of-bounds memory access. A user with read-write credentials can exploit the issue. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. Those who must use SNMPv1 or SNMPv2c should use a complex community string and enhance the protection by restricting access to a given IP address range.

The weakness was disclosed 12/07/2023. The advisory is shared at bugzilla.redhat.com. The identification of this vulnerability is CVE-2022-24807 since 02/10/2022. Technical details are known, but no exploit is available.
