The Linux Kernel, the operating system core itself.
Security Fix(es):
A flaw found in the Linux Kernel. The missing check causes a type confusion when issuing a listentry() on an empty reportlist. 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.

In nftablesupdtable, if nftablestableenable returns an error, nfttransdestroy is called to free the transaction object. nfttransdestroy() calls listdel(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference.(CVE-2023-1095)
