CVE-2026-64182

The CVE-2026-64182 vulnerability concerns the Linux kernel memory subsystem: memblk_nr_poison_inc() and memblk_nr_poison_sub() look up a memory block via find_memory_block_by_id(), which returns a reference to the memory block device. Both helpers use the returned memory block without dropping th...

CVE-2026-64180

CVE-2026-64180 is tied to the Linux kernel memory hotplug path. A memory block reference leak occurs in remove_memory_blocks_and_altmaps() when it calls find_memory_block() and drops the reference too late, causing a leaked memory block device reference during removal of memory blocks/altmaps. Th...
