Loading vulnerability…
In GNOME Keyring before version 3.27.2, pam/gkr-pam-module.c mishandles user credentials by retaining the user's password in a session-child process spawned from the LightDM daemon. As a result, the password may remain accessible in process memory in cleartext beyond its intended use during authentication/session setup. The issue is specifically described as affecting the GNOME Keyring PAM module's handling of the user's password in the LightDM login flow.
