CVE-2026-72047: In the Linux kernel, the following vulnerability has been resolved: ieee802154: ca8210: fix pointer truncation in kfifo

A bug in the Linux kernel's ca8210 wireless driver caused pointer truncation (cutting off part of a memory address) on 64-bit systems. The code was passing only 4 bytes when trying to store 8-byte pointers through a kfifo (a data structure for passing items between parts of the kernel), resulting in corrupted addresses that would crash the system when accessed.
