What should I do about CVE-2026-35553?
Patch when available; restrict driver usage to minimize exposure
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Local arbitrary code execution via registry manipulation in the ACPI driver stack; potential privilege escalation.
Patch when possible
- affectedv11.0.0.0 and earlier
- affectedall versions
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.
