Summary
kmod update
Details

USN-8226-1 added a mitigation to kmod to disable loading the algif_aead module. This update adds the same mitigation to Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS.

Original advisory details:

It was discovered that the Linux kernel algifaead module contained a logic flaw allowing a local attacker to escalate privileges to root. This update to the kmod package disables loading the algifaead module as a measure to mitigate the issue until kernel updates are made available.
