CVE-2025-25568

9.8 criticalEPSS 0.6%

Critical (9.8) in softether vpn. EPSS 0.6% chance of exploitation in the next 30 days.

SoftEtherVPN 5.02.5187 is vulnerable to Use after Free in the Command.c file via the CheckNetworkAcceptThread function. NOTE: the Supplier disputes this because the use-after-free is not in the VPN software, but is instead in a separate tool that has no untrusted input and runs under the user's own privileges (it is a stress-testing tool for a networking stack).
