CVE-2023-53039 Information

Description

In the Linux kernel the following vulnerability has been resolved:

HID: intel-ish-hid: ipc: Fix potential use-after-free in work function

When a reset notify IPC message is received the ISR schedules a work function and passes the ISHTP device to it via a global pointer ishtp_dev. If ish_probe() fails the devm-managed device resources including ishtp_dev are freed but the work is not cancelled causing a use-after-free when the work function tries to access ishtp_dev. Use devm_work_autocancel() instead so that the work is automatically cancelled if probe fails.
