CVE-2022-22155 is an Uncontrolled Resource Consumption vulnerability in Juniper Networks Junos OS, specifically affecting the ACX5448 router. An adjacent attacker can trigger a memory leak in the Flexible PIC Concentrator (FPC) by continuously manipulating IPv6 neighbor state changes with specific timing. This leads to resource exhaustion and a sustained Denial of Service (DoS) condition requiring a manual restart to restore service. The vulnerability has a CVSS score of 6.5 (Medium), indicating it can be exploited by an adjacent attacker with low attack complexity, resulting in high availability impact. There is no confidentiality or integrity impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage regarding this vulnerability.
