Packages
- kmod - tools for managing Linux kernel modules
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 algif_aead module contained a logic
flaw allowing a local attacker to escalate privileges to root. This update
to the kmod package disables loading the algif_aead module as a measure to
mitigate the issue until kernel updates are made available.
