Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a memory leak in error handling paths in the Linux kernel, specifically in the uio hv generic component. If the
vmbus establish gpadl() function fails, the (recv|send) gpadl will not be updated, and the hv uio cleanup() function in the error handling path will not be able to free the corresponding buffer. This can lead to a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
