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.
