1) Missing release of memory after effective lifetime (CVE-ID: CVE-2025-30647)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to missing release of memory after effective lifetime error in the packet forwarding engine (PFE). A remote non-authenticated attacker can cause a Denial-of-Service (DoS).

In a subscriber management scenario, login/logout activity triggers a memory leak, and the leaked memory gradually increments and eventually results in a crash.
