CVE-2026-23094

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> uacce: fix isolate sysfs check condition<br /> <br /> uacce supports the device isolation feature. If the driver<br /> implements the isolate_err_threshold_read and<br /> isolate_err_threshold_write callback functions, uacce will create<br /> sysfs files now. Users can read and configure the isolation policy<br /> through sysfs. Currently, sysfs files are created as long as either<br /> isolate_err_threshold_read or isolate_err_threshold_write callback<br /> functions are present.<br /> <br /> However, accessing a non-existent callback function may cause the<br /> system to crash. Therefore, intercept the creation of sysfs if<br /> neither read nor write exists; create sysfs if either is supported,<br /> but intercept unsupported operations at the call site.
