Descriptions

**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.”.

** EN DISPUTA ** Se descubrió un problema en el subsistema efi en el kernel de Linux hasta la versión 5.1.5. phys_efi_set_virtual_address_map en arch / x86 / platform / efi / efi.c y efi_call_phys_prolog en arch / x86 / platform / efi / efi_64.c manejan mal los errores de asignación de memoria. NOTA: Esta identificación se disputa por no ser un problema porque “Todo el código tocado por el commit referenciado solo se ejecuta en el arranque, antes de que se inicien los procesos del usuario. Por lo tanto, no hay posibilidad de que un usuario sin privilegios lo controle ".
