Patch when possible
- affected<= 12.3.4.8162
- affected< 13.8.2.10019
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.
