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.References:https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=b12fece4c64857e5fab4290bf01b2e0317a88456https://www.openwall.com/lists/oss-security/2023/01/17/3
