Summary

CVE-2022-22071 is a high-severity Use After Free (CWE-416) vulnerability in Qualcomm Apq8053 Firmware. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 34th percentile by exploit likelihood (below the median); CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2022-22071 is a use-after-free vulnerability (CWE-416) affecting multiple Qualcomm Snapdragon platforms, including Auto, Compute, Connectivity, Consumer IOT, Industrial IOT, Mobile, and Voice & Music. The flaw occurs when process shell memory is released via an IOCTL munmap call while process initialization is still underway, allowing memory to be accessed after it has been freed.

A local attacker with no privileges or user interaction can trigger the condition to achieve arbitrary code execution or memory corruption with high impact on confidentiality, integrity, and availability. The CVSS 8.4 vector reflects local attack surface combined with the potential for full system compromise on affected devices.

Qualcomm addressed the issue in its May 2022 security bulletin, which includes patches for impacted chipsets. The vulnerability is also listed in CISA's Known Exploited Vulnerabilities catalog, confirming observed in-the-wild exploitation. The current EPSS score of 0.0055 indicates low but non-zero exploitation probability.
