CVE-2021-47071
In the Linux kernel, the following vulnerability has been resolved: uio_hv_generic: Fix a memory leak in error handling paths If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be updated and 'hv_uio_cleanup()' in the error handling path…
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: uio_hv_generic: Fix a memory leak in error handling paths If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be updated and 'hv_uio_cleanup()' in the error handling path will not be able to free the corresponding buffer. In such a case, we need to free the buffer explicitly.
