MEDIUM 6.5EPSS 1.48%
Does this matter?
Lower severity and a low EPSS score (1.48%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. Under certain conditions, the integrity of EAPOL-Key messages is not checked, leading to a decryption oracle.
