In the Linux kernel, the following vulnerability has been resolved:

uacce: fix isolate sysfs check condition

uacce supports the device isolation feature. If the driver implements the isolateerrthresholdread and isolateerrthresholdwrite callback functions, uacce will create sysfs files now. Users can read and configure the isolation policy through sysfs. Currently, sysfs files are created as long as either isolateerrthresholdread or isolateerrthresholdwrite callback functions are present.

However, accessing a non-existent callback function may cause the system to crash. Therefore, intercept the creation of sysfs if neither read nor write exists; create sysfs if either is supported, but intercept unsupported operations at the call site.
