Description

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 isolate_err_threshold_read and isolate_err_threshold_write 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 isolate_err_threshold_read or isolate_err_threshold_write 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.
