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.

Fix and mitigation
WAF and other mitigations
Can a WAF block it? No. The attack needs local access to the machine, so a WAF is not on its path.
Also consider: patch
Based on the attack vector (local or physical access). We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Common questions
Is CVE-2023-33107 being exploited?
Yes. CVE-2023-33107 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.
How severe is CVE-2023-33107?
CVE-2023-33107 is rated High with a CVSS score of 8.4. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2023-33107?
Yes. A fix has been recorded for CVE-2023-33107. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2023-33107 affect?
CVE-2023-33107 affects qualcomm:315_5g_iot_modem_firmware, qualcomm:apq8017_firmware, qualcomm:apq8064au_firmware, qualcomm:aqt1000_firmware, and 26 further products or versions. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
