CVE-2024-23814 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. The integrated ICMP service of the network stack of affected devices can be forced to exhaust its available memory resources when receiving specially crafted messages targeting IP fragment re-assembly. This could allow an unauthenticated remote attacker to cause a temporary denial of service condition of the ICMP service, other communication services are not affected. EPSS estimates a 0.57% chance of exploitation in the next 30 days.

Description

The integrated ICMP service of the network stack of affected devices can be forced to exhaust its available memory resources when receiving specially crafted messages targeting IP fragment re-assembly.
