CISA KEV Advisory
Qualcomm Multiple Chipsets Use-After-Free Vulnerability
Multiple Qualcomm chipsets contain a use-after-free vulnerability when process shell memory is freed using IOCTL munmap call and process initialization is in progress.
Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.
Risk Analysis
Multiple Qualcomm chipsets are affected by a use-after-free vulnerability that occurs during memory management. This high-severity flaw is confirmed to be exploited in the wild (KEV), making it a critical issue despite a low EPSS score.
This vulnerability is actively being exploited in the wild, as confirmed by its presence in CISA's KEV catalog.
Users of affected Qualcomm chipsets should apply any available firmware updates or patches from their device manufacturers. Keeping device software up to date is crucial for security.
Technical Analysis
CVE-2022-22071 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2022-22071 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
