CVE-2025-2796
Received duplicate encrypted packets, which should be dropped under normal anti-replay protection, will instead be forwarded due to this vulnerability.
Does this matter?
Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.

Received duplicate encrypted packets, which should be dropped under normal anti-replay protection, will instead be forwarded due to this vulnerability.
