What is CVE-2024-7095?
CVE-2024-7095 is a medium-severity denial of service vulnerability in Arista Networks EOS, published on 10 Jan 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
On affected platforms running Arista EOS with SNMP configured, if “snmp-server transmit max-size” is configured, under some circumstances a specially crafted packet can cause the snmpd process to leak memory. This may result in the snmpd process being terminated (causing SNMP requests to time out until snmpd is restarted) and memory pressure for other processes on the switch. Increased memory pressure can cause processes other than snmpd to be at risk for unexpected termination as well.
Weakness: CWE-401
