CVE-2026-46284
In the Linux kernel, the vulnerability (CVE-2026-46284) affects early boot parameter parsing for hugepages. When hugepages, hugepagesz, or default_hugepagesz are supplied on the kernel command line without an '=' separator, early parsing passes NULL to hugetlb_add_param(), which dereferences NULL...
