CVE-2026-56101

OpenBSD before commit 1ee99df contains an inverted comparison in the ieee80211_michael_mic_failure() function within sys/net80211/ieee80211_crypto_tkip.c. The reversed TKIP MIC failure countermeasure window check allows unauthenticated attackers within RF range to send two malformed TKIP frames s...
