How do I patch CVE-2022-22071?

No patch has shipped for CVE-2022-22071 yet — track the qualcomm apq8053 firmware advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2022-22071 across my infrastructure?

Inventory every qualcomm apq8053 firmware deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2022-22071 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2022-22071?

O3 detects and blocks CVE-2022-22071 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2022-22071 actively exploited in the wild?

Yes. There are 2 known exploit references for CVE-2022-22071, including 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2022-22071?

CVE-2022-22071 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 37th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Is CVE-2022-22071 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2022-22071 (Qualcomm Multiple Chipsets Use-After-Free Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2023-12-05. CISA required all US federal civilian agencies to remediate this vulnerability by 2023-12-26. The required action was: Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2022-22071?

CVE-2022-22071 is classified as Use After Free (CWE-416). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Which products and versions are affected by CVE-2022-22071?

CVE-2022-22071 affects qualcomm apq8053 firmware; qualcomm ar8031 firmware; qualcomm ar8035 firmware; qualcomm csra6620 firmware, and 86 more product(s). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2022-22071 published, and has it been updated?

CVE-2022-22071 was published on June 14, 2022 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
