An issue in wpa_supplicant all versions before v.2.12 allows a local attacker to bypass proper network context and AKMP matching for PMKSA caching via missing validation in the driver based PMKSA selection path in wpa.c
AI Analysis
Technical Summary
CVE-2026-78807 describes a security issue in wpa_supplicant affecting all versions prior to 2.12. The vulnerability arises from missing validation in the driver-based PMKSA selection path within the wpa.c component, which allows a local attacker to bypass proper network context and AKMP (Authentication and Key Management Protocol) matching for PMKSA (Pairwise Master Key Security Association) caching. This could result in the attacker leveraging cached credentials improperly.
Potential Impact
The vulnerability allows a local attacker to bypass intended security checks related to network context and AKMP matching in PMKSA caching. This could potentially lead to unauthorized use of cached network credentials, undermining the security of wireless network authentication processes.
Mitigation Recommendations
A fix is available in wpa_supplicant version 2.12. Users and administrators should upgrade to version 2.12 or later to remediate this vulnerability. No additional mitigation steps are indicated.
