# Dell PowerStore: integer overflow lets nearby attacker bypass volume bounds checks

Link for people: https://infrastack.ai/live/CVE-2026-107523 (this .md is for agents)

Dell PowerStore storage arrays contain an integer overflow that lets an attacker bypass volume bounds checks. A successful attack could destroy data or cause denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:PowerStoreT OS affected >= 5.1.0.0, < 5.1.0.0-2798105 fixed 5.1.0.0-2798105

## How to check

In PowerStore Manager (Settings > Software), or via the REST API, read the PowerStoreT OS version. Exposed if it is 5.1.x earlier than 5.1.0.0-2798105 on any model listed in DSA-2026-479. Adjacent-network access (same L2/storage network) is needed to attack it.

## Fix

Update PowerStoreT OS to 5.1.0.0-2798105 or later (per DSA-2026-479; version as reported by securityonline and Eventus, not visible in the part of Dell's page I could read).

Dell's description confirmed on its page (adjacent attacker, volume bounds bypass, data destruction/DoS). Version range and fix come from secondary write-ups (securityonline, Eventus) because Dell's page was truncated, so nothing is marked verified. No exploitation reported. Workaround reported by Eventus: restrict network access to NAS services (TFTP/NFS) and management interfaces; not tied specifically to this CVE. Lower bound of range is unclear (the 4.x line may also be affected).

## From the sources

Dell PowerStore contains an integer overflow vulnerability. An adjacent attacker could exploit it to bypass volume bounds checks, potentially leading to data destruction or denial of service.
