The fix you mentioned was backported into containerd 1.5.10 via containerd/containerd#6503. That release contained a security fix as well, and has already been updated in main, 1.23 and 1.22. Currently, they're available as release candidates, only:

Branch	PR	Release candidate
main	#1573	-/-
1.23	#1576	1.23.4-rc.1+k0s.0
1.22	#1575	1.22.7-rc.1+k0s.0

That said, the containerd 1.6 upgrade is on the radar, of course.
