SUSE CVE-2026-55428

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the tailnet coordinator validates that an agent's Addresses derive from its authenticated UUID but applies no equivalent check to AllowedIPs. The coordinato...

FreeBSD : FreeBSD -- Missing MAC validation in wg(4) packet decryption (3840a83e-8bb8-11f1-a6ab-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 3840a83e-8bb8-11f1-a6ab-bc241121aa0a advisory. After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check...

FreeBSD -- Missing MAC validation in wg(4) packet decryption

Problem Description: After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. Impact: A remote attacker who can send UDP...
