# CVE-2022-22071: Qualcomm Multiple Chipsets Use-After-Free Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Qualcomm Multiple Chipsets. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2023-12-05, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2023-12-26 ; treat that as the outer limit, not the target.
- EPSS 0.4% , percentile 34: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 34% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.

## What it is

Possible use after free when process shell memory is freed using IOCTL munmap call and process initialization is in progress in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music

## Affected products (CVE record)

- qualcomm CVSS 3.1: 8.4 `CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2023-12-05; federal due date 2023-12-26. Known ransomware use: Unknown.
- CISA required action: Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.41% probability of exploitation activity in the next 30 days; percentile 34.
