CVE-2023-22414

A Missing Release of Memory after Effective Lifetime vulnerability in Flexible PIC Concentrator (FPC) of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker from the same shared physical or logical network, to cause a heap memory leak and leading to FPC crash. On all Junos PTX Series and QFX10000 Series, when specific EVPN VXLAN Multicast packets are processed, an FPC heap memory leak is observed. The FPC memory usage can be monitored using the CLI command "show heap extensive". Following is an example output.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For juniper's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
