CVE-2021-47071 Open this link in a new tabHow to fix?
There is no fixed version for Centos:8 perf.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
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.
