CVE-2024-5290 (GCVE-0-2024-5290)

Vulnerability from cvelistv5 – Published: 2024-08-07 08:14 – Updated: 2024-09-18 15:39

Summary

An issue was discovered in Ubuntu wpa_supplicant that resulted in loading of arbitrary shared objects, which allows a local unprivileged attacker to escalate privileges to the user that wpa_supplicant runs as (usually root). Membership in the netdev group or access to the dbus interface of wpa_supplicant allow an unprivileged user to specify an arbitrary path to a module to be loaded by the wpa_supplicant process; other escalation paths might exist.

Severity ?

8.8 (High)
