In the Linux kernel, the following vulnerability has been resolved:
HID: intel-ish-hid: fix NULL-ptr-deref in ishtp_bus_remove_all_clients
During a warm reset flow, the cl->device pointer may be NULL if the
reset occurs while clients are still being enumerated. Accessing
cl->device->reference_count without a NULL check leads to a kernel panic.
This issue was identified during multi-unit warm reboot stress clycles.
Add a defensive NULL check for cl->device to ensure stability under
such intensive testing conditions.
KASAN: null-ptr-deref in range [0000000000000000-0000000000000007]
Workqueue: ish_fw_update_wq fw_reset_work_fn
Call Trace:
ishtp_bus_remove_all_clients+0xbe/0x130 [intel_ishtp]
ishtp_reset_handler+0x85/0x1a0 [intel_ishtp]
