Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. mde_equal() compares its first argument to itself CWE-697. CVSS 3.1: 3.1 Low CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N src/ft.c:385 Introduced 1.14, commit 2c0234e1 return memcmp(mde1, mde1, mde1[1] + 2) == 0; mde2 is never read, so the check always passes. Its only caller is ft_parse_ies() (ft.c:667), where it should confirm the target AP echoed the Mobility Domain element the station sent on the 802.11r FT Authentication Response and FT-over-DS paths. Not an authentication bypass - __ft_rx_associate() compares correctly at ft.c:496 and the FTE MIC there is keyed on PMK-R1 - but a response carrying an arbitrary mobility domain ID and FT capability flags passes the authentication stage into FTE parsing and key derivation. Finding 4 sits on that path, one call later.
