CVE-2024-50017 x86/mm/ident_map: Use gbpages only where full GB page should be mapped.

In the Linux kernel, the following vulnerability has been resolved: x86/mm/identmap: Use gbpages only where full GB page should be mapped. When identpudinit uses only GB pages to create identity maps, large ranges of addresses not actually requested can be included in the resulting table; a 4K...

CVE-2024-50017

CVE-2024-50017 affects the Linux kernel’s identity-mapping code (x86/mm/ident_map). When ident_pud_init() creates identity maps using only GB pages, it can map large address ranges not requested (a 4K request could yield a full 1GB mapping), potentially including BIOS-reserved areas. This enables...
