Why is there no patch for the copyfail vulnerability in OpenEuler 2203 LTS?

The affected versions listed here don’t include 2203LTS; if 2203LTS SP is affected, does that mean 2203LTS is also affected?

I tried it yesterday and escalated directly to root.

There are patch packages available, should be.

This is sp4, isn’t it?

sp4 的包不是sp1-sp4都能装的

I don’t understand what you mean. Can you tell me more details?

The sp4 package is compatible with all 2203 versions.

So, is the LTS not fixed? Is upgrading to SP4 the only solution?

After upgrading the kernel in this patch, the display on tty2 shows only squares, while tty1 is normal.
