The function hid_ishtp_cl_deinit() is called before ishtp_hid_remove(), which can lead to accessing freed memory or resources during the removal process.

01 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove() The system can experience a random crash a few minutes after the driver is removed. This issue occurs due to improper handling of memory freeing in the ishtp_hid_remove() function. The function currently frees the `driver_data` directly within the loop that destroys the HID devices, which can lead to accessing freed memory. Specifically, `hid_destroy_device()` uses `driver_d... • https://git.kernel.org/stable/c/0b28cb4bcb17dcb5fe0763fc3e1a94398b8f6cf6 •

When header digests are enabled, a target might send a packet with an invalid header length (e.g. 255), causing nvme_tcp_verify_hdgst() to access memory outside the allocated area and cause memory corruptions by overwriting it with the calculated digest.
