[Kernel-packages] [Bug 1956793] Re: linux-azure-cvm: Avoid leaking guest memory when communicating with the host
This bug is awaiting verification that the linux-azure- cvm/5.4.0-1068.71+cvm1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification- done-focal'. If the problem still exists, change the tag 'verification- needed-focal' to 'verification-failed-focal'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
