Patch when possible
- affectedversion E1010-1.1ASL
- affectedversion E2022 - 3.1.2A
- affectedversion E2022 - 3.1.5AV
- affectedversion E2022 - 1.1ASL
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.
