CVE-2023-1073: Buffer Overflow

First published: Sun Feb 26 2023(Updated: )

A flaw found in the Linux Kernel. The missing check causes a type confusion when issuing a list_entry() on an empty report_list. The problem is caused by the assumption that the device must have valid report_list. While this will be true for all normal HID devices, a suitably malicious device can violate the assumption.
