Network traffic leakage outside VPN tunnel
Published Sep 16, 2024 · Updated Apr 2, 2026
A kernel logic issue in affected Apple operating systems allows network traffic to leak outside an active VPN tunnel. Apple identifies the locus only as the Kernel and has not published which check or routing decision incorrectly permits the bypass. Exposure requires an active VPN configuration; affected traffic can traverse a non-tunnel path, removing the tunnel’s confidentiality protection.
