Patch when possible
- affected>= 22.0.0 and <= 22.0.1F-32
- affected>= 21.3.0 and <= 21.3.0M-13
- affected>= 1.0.0 and < 21.3.0
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
