Discussion

NetBSD SO_LINGER DIAGNOSTIC Checking Local Denial of Service Vulnerability

NetBSD is susceptible to a local denial of service condition due to a kernel-level bug in the SO_LINGER diagnostics checking code. NetBSD versions 2.x are affected.

This issue only affects NetBSD kernels compiled with the 'DIAGNOSTIC' directive enabled.

This issue allows local attackers to panic the kernel, denying further service to legitimate users.
