CVE-2022-50669 Details
Description
In the Linux kernel, the following vulnerability has been resolved: misc: ocxl: fix possible name leak in ocxl_file_register_afu() If device_register() returns error in ocxl_file_register_afu(), the name allocated by dev_set_name() need be freed. As comment of device_register() says, it should use put_device() to give up the reference in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanup(), and info is freed in info_release().
A name leak vulnerability has been identified in the Linux kernel's OCXL file registration process for Accelerator Function Units (AFUs). This issue arises when the 'device_register()' function returns an error, as the name set by 'dev_set_name()' is not properly freed. The vulnerability exists in the 'ocxl_file_register_afu()' function within the OCXL driver. The problem can be exploited by causing 'device_register()' to fail, leading to a memory leak of the allocated name.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
