Comment 1 Scott Gayou 2018-07-20 19:39:13 UTC

Upstream workaround in gnome-bluetooth: https://gitlab.gnome.org/GNOME/gnome-bluetooth/commit/6b5086d42ea64d46277f3c93b43984f331d12f89

Note that the actual bug is not in gnome-bluetooth.

RHEL is not affected as RHEL-7 is running Gnome 3.26, which is not impacted.

Mitigation:

Disable Bluetooth.

Comment 9 Scott Gayou 2018-08-09 18:14:10 UTC

It appears that a fix was merged upstream and may be available in a future release of BlueZ 5.51. gnome-bluetooth-3.28.2 will take advantage of this fix.
