CVE-2023-54027 (CNNVD-202512-4673)
中文标题:
Linux kernel 安全漏洞
英文标题:
iio: core: Prevent invalid memory access when there is no parent
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IIO核心在设备无父节点时尝试访问空指针，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: iio: core: Prevent invalid memory access when there is no parent Commit 813665564b3d ("iio: core: Convert to use firmware node handle instead of OF node") switched the kind of nodes to use for label retrieval in device registration. Probably an unwanted change in that commit was that if the device has no parent then NULL pointer is accessed. This is what happens in the stock IIO dummy driver when a new entry is created in configfs: # mkdir /sys/kernel/config/iio/devices/dummy/foo BUG: kernel NULL pointer dereference, address: ... ... Call Trace: __iio_device_register iio_dummy_probe Since there seems to be no reason to make a parent device of an IIO dummy device mandatory, let’s prevent the invalid memory access in __iio_device_register when the parent device is NULL. With this change, the IIO dummy driver works fine with configfs.
