What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

In the Linux kernel, the following vulnerability has been resolved:

HID: steam: Rearrange teardown sequence

This fixes a narrow window during the teardown sequence where callbacks could still be scheduled during cleanup that would then have a dangling pointer to the now-freed steam struct.

This also puts work canceling for rumble and mode switch in steam_unregister, as that shouldn't persist while the client hdev is open.
