TPS-2022-001 tmpfs induced panic
Overview
An unprivileged user, including users in a zone, with access to a tmpfs
can
induce a system panic resulting in the system rebooting.
Actions taken by Joyent
A new platform image is available in the release
channel (20220118T183559Z
),
and updated SmartOS boot images are available in Manta.
Actions You Need to Take
Triton Operators
This platform should be installed and assigned to all SmartOS compute nodes. You can use the following commands to prepare the new platform image.
sdcadm platform install -C release 20220118T183559Z
sdcadm platform assign 20220118T183559Z $(sdc-server lookup system_type=SunOS)
Once each compute node is rebooted, it can no longer be affected by this issue.
SmartOS stand-alone Users
Stand alone SmartOS servers should be rebooted to the appropriate image.
