Linux Kernel 7.0.5 has been released, addressing a critical IPsec bug that previously allowed network traffic corruption due to improper ownership checks on shared UDP memory pages. The update introduces safety flags to align with TCP behavior, ensuring the kernel copies data before modification, which prevents silent packet loss and instability in VPNs. System administrators are advised to verify their kernel version and monitor logs for any dropped packets post-update to maintain reliable encrypted tunnels. The patch is designed to enhance performance without compromising functionality, particularly for users running popular VPN software like WireGuard and OpenVPN
Linux Kernel 7.0.5 released
Linux Kernel 7.0.5 patches a critical IPsec bug that silently corrupted network traffic by decrypting shared UDP memory pages without proper ownership checks. The update adds missing safety flags to match TCP behavior and forces the kernel to copy data before modifying it, preventing silent packet loss and VPN instability. System administrators should verify their running kernel version includes this fix and monitor system logs for dropped packets after upgrading. Rolling out the patch ensures encrypted tunnels stay reliable without sacrificing performance on standard network configurations.
