CVE-2025-71118

In the Linux kernel, the following vulnerability has been resolved: ACPICA: Avoid walking the Namespace if start_node is NULL Although commit 0c9992315e73 ("ACPICA: Avoid walking the ACPI Namespace if it is not there") fixed the situation when both start_node and acpi_gbl_root_node are NULL, the Linux kernel mainline now still crashed on Honor Magicbook 14 Pro [1]. That happens due to the access to the member of parent_node in acpi_ns_get_next_node(). The NULL pointer dereference will always happen, no matter whether or not the start_node is equal to ACPI_ROOT_OBJECT, so move the check of start_node being NULL out of the if block. Unfortunately, all the attempts to contact Honor have failed, they refused to provide any technical support for Linux. The bad DSDT table's dump could be found on GitHub [2]. DMI: HONOR FMB-P/FMB-P-PCB, BIOS 1.13 05/08/2025 [ rjw: Subject adjustment, changelog edits ]

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: ACPICA: Evitar recorrer el Namespace si start_node es NULL Aunque el commit 0c9992315e73 ('ACPICA: Evitar recorrer el ACPI Namespace si no está presente') arregló la situación cuando tanto start_node como acpi_gbl_root_node son NULL, la línea principal del kernel de Linux ahora todavía fallaba en Honor Magicbook 14 Pro [1]. Eso ocurre debido al acceso al miembro de parent_node en acpi_ns_get_next_node(). La desreferencia del puntero NULL siempre ocurrirá, sin importar si start_node es igual a ACPI_ROOT_OBJECT o no, así que mueva la comprobación de que start_node es NULL fuera del bloque if. Desafortunadamente, todos los intentos de contactar a Honor han fallado, se negaron a proporcionar cualquier soporte técnico para Linux. El volcado de la tabla DSDT defectuosa se puede encontrar en GitHub [2]. DMI: HONOR FMB-P/FMB-P-PCB, BIOS 1.13 05/08/2025 [ rjw: Ajuste del asunto, ediciones del registro de cambios ]
