Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.54%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In pam/gkr-pam-module.c in GNOME Keyring before 3.27.2, the user's password is kept in a session-child process spawned from the LightDM daemon. This can expose the credential in cleartext.
