It does not behave as described on EndeavorOS (arch-based) running kernel 6.19.14-arch1-1. I receive the error:
Password: su: Authentication token manipulation error
I'm guessing this means it's already patched?
same result on my arch machine as well.
yes, it was reported on march 23rd, patches on april 1.
you are reading about it now because it has been patched.
