Threats affecting pkg:github/OpenBSD

CVE-2026-56101 is a vulnerability in OpenBSD's handling of TKIP MIC failure countermeasures in the ieee80211_michael_mic_failure() function. An inverted comparison logic allows unauthenticated attackers within RF range to cause denial of service by sending two malformed TKIP frames separated by more than 60 seconds. This triggers deauthentication of all associated TKIP stations and blocks reassociation for up to 90 seconds, while legitimate MIC failures within the expected window are ignored, potentially allowing key-recovery attempts to go undetected.
