VMware NSX Data Center for vSphere 6.4.14 | 20 OCT 2022 | Build 20609341

Check for additions and updates to these release notes.


WHAT'S NEW

VMware NSX Data Center for vSphere 6.4.14 fixes a number of customer bugs and
addresses a security vulnerability documented in VMSA-2022-0027. Updated XStream
to version 1.4.19 to resolve CVE-2021-39144.

 * This security vulnerability impacts NSX for vSphere in both VCF and non-VCF
   environments.

 * The security fix applies to the NSX Manager only, however an upgrade to
   6.4.14 involves a full upgrade, as the release contains other component
   fixes.

See the NSX Data Center for vSphere 6.4.13 Release Notes for upgrade and
installation details and current known issues.


RESOLVED ISSUES

 * Fixed Issue 2989776: VMkernel logs filled up by, “Cannot add Arp VMI, reached
   max limit of 1.”
   
   Due to duplicate MAC issue, VMware ESXi log file (/var/log/vmkernel.log) is
   rapidly filled up by excessive messages indicating max ARP limit had been
   reached.  Resolution: NSX for vSphere 6.4.14 has reduced the default log
   level for this message from Error to Debug.
   
   

 * Fixed Issue 3003814: NSX Manager unresponsive until reboot.
   
   Unavailability of NSX Manager.
   
   

 * Fixed Issue 3020991: Multiple ESX hosts PSOD with large number of pending ARP
   entries across DRs.
   
   When workloads generate larger number of TCP/UDP traffic for non-existent IPs
   (typically by a scanner tool), DRs initiate ARPs to those IPs. DRs couldn't
   complete processing these large ARPs resulting in ESX watchdog process to
   PSOD the host.
