Cisco Nexus 9000 Series Fabric Switches in ACI Mode SNMP Denial of Service Vulnerability
Notes
Summary
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco Nexus 9000 Series Fabric Switches in ACI mode could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper processing when parsing SNMP requests. An attacker could exploit this vulnerability by continuously sending SNMP queries to a specific MIB of an affected device. A successful exploit could allow the attacker to cause a kernel panic on the device, resulting in a reload and a DoS condition.
Note: This vulnerability affects SNMP versions 1, 2c, and 3. To exploit this vulnerability through SNMPv1 or SNMPv2c, the attacker must have a valid read-only SNMP community string for the affected system. To exploit this vulnerability through SNMPv3, the attacker must have valid SNMP user credentials for the affected system.
Cisco has released software updates that address this vulnerability. There are workarounds that address this vulnerability.
This advisory is part of the February 2026 Cisco FXOS and NX-OS Software Security Advisory Bundled Publication. For a complete list of the advisories and links to them, see Cisco Event Response: February 2026 Semiannual Cisco FXOS and NX-OS Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75740"].
Vulnerable Products
This vulnerability affects Cisco Nexus 9000 Series Fabric Switches in ACI mode when both of the following conditions are met:
The SNMP feature is enabled.
At least one authentication, authorization, and accounting (AAA) provider is configured with a DNS name (hostname or fully qualified domain name (FQDN)) or an IPv6 address instead of an IPv4 address.
For information about which Cisco software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.
Determine the SNMP Configuration
To determine whether a device has SNMPv1, SNMPv2c, or SNMPv3 enabled, use the show snmp summary CLI command from the switch CLI, as shown in the following example:
leaf101# show snmp summary
<Admin State : enabled, running (pid:26630)
Local SNMP engineID: [Hex] 8000000903003A9C451079 [Dec] 128:000:000:009:003:000:058:156:069:016:121
---------------------------------------------------------------------- Community Context Status ---------------------------------------------------------------------- snmp ok
---------------------------------------------------------------------- User Authentication Privacy Status ---------------------------------------------------------------------- snmpv3-user hmac-sha2-256 none ok
If the Admin State is enabled and there is an entry under Community (SNMPv1 or SNMPv2c) or User (SNMPv3), SNMP is configured and running. For information regarding SNMP configuration from the Cisco Application Policy Infrastructure Controller (APIC) web UI, see the Configure SNMP in ACI ["https://www.cisco.com/c/en/us/support/docs/cloud-systems-management/application-policy-infrastructure-controller-apic/221836-configure-snmp-in-aci.html"] TechNote.
Determine the AAA Configuration
To determine the AAA configuration, use the APIC web UI and complete the following steps:
Go to Admin > AAA.
Click Authentication.
Click Providers.
If any AAA providers are configured with a DNS name (hostname or FQDN) or an IPv6 address instead of an IPv4 address and SNMP is enabled and active, the device is in a vulnerable configuration.

Indicators of Compromise
This vulnerability causes SNMPd processes to consume memory until an out-of-memory (OOM) condition results in a kernel panic and a device reload. To check for this issue, use the following commands with administrative privileges from the switch CLI.
To check the number of SNMPd processes, use ps -eaf | grep -i snmpd.
Leaf101# ps -eaf | grep snmpd
root 16944 18558 0 Aug08 ? 00:00:00 [snmpd] <defunct>
root 17523 18558 0 Aug08 ? 00:00:00 [snmpd] <defunct>
root 17859 18558 0 Aug08 ? 00:00:00 [snmpd] <defunct>
root 18036 18558 0 Aug08 ? 00:00:00 [snmpd] <defunct>
root 18558 12508 0 Aug08 ? 00:27:50 /isan/bin/snmpd -f -s -d udp:161 udp6:161 tcp:161
root 20075 18558 0 Aug08 ? 00:00:00 /isan/bin/snmpd -f -s -d udp:161 udp6:161 tcp:161
If the number of SNMPd processes is more than 10 and is increasing over time, the devices may be impacted by this vulnerability. Processes that show <defunct> do not consume memory but are also a possible indication of this vulnerability.
To get the amount of memory that has been used and is not free, use free -k | awk 'NR==2 {printf "Memory-used: %.2f%%\n", ($2-$7)/$2*100}'.
Leaf101# free -k | awk 'NR==2 {printf "Memory-used: %.2f%%\n", ($2-$7)/$2*100}'
Memory-used: 45.03%
If the amount of memory used is more than 85% and is increasing over time, the device is approaching an OOM condition and may reload. The Cisco Technical Assistance Center ["https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html"] (TAC) can help to recover a device from the high memory condition.
Workarounds
A workaround for this vulnerability exists for AAA providers that are configured with IPv4 DNS names. Update all AAA providers from a DNS name (hostname or FQDN) to an IPv4 address configuration. For more information about AAA configuration, see Cisco Application Centric Infrastructure Fundamentals, Release 6.1(x) ["https://www.cisco.com/c/en/us/td/docs/dcn/aci/apic/6x/aci-fundamentals/cisco-aci-fundamentals-61x/aaa-60x.html?bookSearch=true"].
There is no workaround for IPv6 configurations.
While this workaround has been deployed and proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.

"details": "A workaround for this vulnerability exists for AAA providers that are configured with IPv4 DNS names. Update all AAA providers from a DNS name (hostname or FQDN) to an IPv4 address configuration. For more information about AAA configuration, see Cisco Application Centric Infrastructure Fundamentals, Release 6.1(x) [\"https://www.cisco.com/c/en/us/td/docs/dcn/aci/apic/6x/aci-fundamentals/cisco-aci-fundamentals-61x/aaa-60x.html?bookSearch=true\"].\r\n\r\nThere is no workaround for IPv6 configurations.\r\n\r\nWhile this workaround has been deployed and proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.",
