CVE-2021-47070

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak has been resolved in the Linux kernel. The issue occurred in the uio hv generic module, where memory allocated by vmbus alloc ring() at the beginning of the probe function was never freed in the error handling path. The missing vmbus free ring() call has been added to fix the issue. Note that the memory was already freed in the .remove function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
