DISPUTED An issue was discovered in the efi subsystem in the Linux
kernel through 5.1.5. phys_efi_set_virtual_address_map in
arch/x86/platform/efi/efi.c and efi_call_phys_prolog in
arch/x86/platform/efi/efi_64.c mishandle memory allocation failures. NOTE:
This id is disputed as not being an issue because “All the code touched by
the referenced commit runs only at boot, before any user processes are
started. Therefore, there is no possibility for an unprivileged user to
control it.”.
