- Summary
- cxl/region: Fix cxl_region leak, cleanup targets at region delete
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Fix cxl_region leak, cleanup targets at region delete
When a region is deleted any targets that have been previously assigned to that region hold references to it. Trigger those references to drop by detaching all targets at unregister_region() time.
Otherwise that region object will leak as userspace has lost the ability to detach targets once region sysfs is torn down.
