Bug description:
  [Impact]
  When running with the HWE kernel (5.4 didn't support altnames), altnames 
containing garbage (uninitialized memory) may get assigned to a NIC. This is 
100% reproducible on arm64. The upstream commit message suggests that this has 
been seen to cause segfaults.

  [Test Case]
  1) echo 1 > /sys/class/net/enp189s0f0/device/sriov_numvfs
  2) ip a
  3)
  10: eno1v0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group 
default qlen 1000
      link/ether 1e:d8:e1:e9:ae:25 brd ff:ff:ff:ff:ff:ff
      altname @▒ު▒
      altname enp125s0f0v0
  11: enp189s0f0v0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group 
default qlen 1000
      link/ether 76:ea:f4:65:dd:33 brd ff:ff:ff:ff:ff:ff
      altname ▒b▒ު▒
      altname ▒▒▒▒▒▒

  [Fix]
  There's a one liner upstream fix that simply initializes a variable:
  
https://github.com/systemd/systemd/commit/61fd7d6720c562c88ab79062ff8d131e5e3c7b1b

  [What Could Go Wrong]
  The fix itself is innocuous - just initializing a variable to NULL. So the 
real risk here would seem to be limited to the common risks in updating a core 
package in the Ubuntu distribution.
