CVE-2018-14424 is a vulnerability of currently unknown severity. The daemon in GDM through 3.29.1 does not properly unexport display objects from its D-Bus interface when they are destroyed, which allows a local attacker to trigger a use-after-free via a specially crafted sequence of D-Bus method calls, resulting in a denial of service or potential code execution.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
