CVE-2025-71118 (CNNVD-202601-2437)
中文标题:
Linux kernel 安全漏洞
英文标题:
ACPICA: Avoid walking the Namespace if start_node is NULL
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于未检查start_node是否为NULL，可能导致空指针取消引用。
英文描述:
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].
