# CVE-2023-33106: Qualcomm Multiple Chipsets Use of Out-of-Range Pointer Offset 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 0.8% , percentile 56: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 56% of all scored CVEs (moderate). 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

Memory corruption while submitting a large list of sync points in an AUX command to the IOCTLKGSLGPUAUXCOMMAND.

## Affected products (CVE record)

- Qualcomm, Inc. Snapdragon: AR8035, CSRA6620, CSRA6640, FastConnect 6200, FastConnect 6700, FastConnect 6800, FastConnect 6900, FastConnect 7800, Flight RB5 5G Platform, QAM8255P, QAM8295P, QAM8650P

## Severity

- 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): 0.79% probability of exploitation activity in the next 30 days; percentile 56.
