I've tested this on SLE-15SP1 GM kernel which is older than the fix and
this version still triggers the crash. Technically we could even pass
all zeroes which would simply leave all console parameters unchanged and
it'd still work because the ioctl implementation sets a flag in the
freed memory anyway. But that behavior might change in the future so
I've decided to just set the rows and cols to the values queried from
kernel.
