Exploiting this vulnerability can allow an attacker, operating remotely, to gain unauthorized access to protecte...

CVE-2025-21677

CVE-2025-21677 describes a Linux kernel PFCP issue where the device is destroyed along with the UDP socket’s netns. The root cause is that pfcp_newlink() links the PFCP device to dev_net(dev) rather than the socket’s netns, so removing netns ns1 can leave the device alive in dev_net(dev) and trig...
