CVE-2026-64182

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drivers/base/memory: fix memory block reference leak in poison accounting<br /> <br /> memblk_nr_poison_inc() and memblk_nr_poison_sub() look up a memory block<br /> via find_memory_block_by_id(), which acquires a reference to the memory<br /> block device.<br /> <br /> Both helpers use the returned memory block without dropping that<br /> reference, leaking the device reference on each successful lookup. Drop<br /> the reference after updating nr_hwpoison.
