wolfSSL has released an update to wolfGuard, our FIPS-validated algorithm port of WireGuard. We recommend updating.

Highlights from this release:

AES-GCM crash fix: resolves a kernel panic on kernels dated after March 2026.

Cookie security fix: sensitive cryptographic material is now reliably wiped on all validation error paths.

Configuration sync fix: corrects a logic error in peer sync that could leave configuration state incorrect.

Memory leak fix: resolves a SHA object leak in the Noise handshake (significant on busy gateways over time).

Stability and compatibility: improvements for kernel 7.x, IPv6 on newer kernels, and ratelimiter correctness.
