Hi!
There's a security problem in pkexec vs. kernel interaction. Impact is
local root. If you want to get root on someone else's system, it
should be easy right now. It is fixed in 5.18, 5.10.120, and latest
4.9 and 4.19 kernels.
Do you have untrusted users on your system and you need pkexec?
Best regards,
Pavel
