Description

In the Linux kernel, the following vulnerability has been resolved: HID: bpf: abort dispatch if device destroyed The current HID bpf implementation assumes no output report/request will go through it after hid_bpf_destroy_device() has been called. This leads to a bug that unplugging certain types of HID devices causes a cleaned- up SRCU to be accessed. The bug was previously a hidden failure until a recent x86 percpu change [1] made it access not-present pages. The bug will be triggered if th
