CVE-2026-107523Dell PowerStore 500T integer overflow
CVE-2026-107523 is a integer overflow in Dell PowerStore 500T, rated high (8.7 on CVSS 3.1).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Awaiting Analysis
What it is
A calculation wraps around, so a size or count ends up far smaller or larger than intended, often leading to memory corruption.
How it is reached
An attacker can exploit it from the same local network segment, with an ordinary user account, and nobody has to click anything.
What an attacker gains
A successful attack can change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker crash the process, read memory, or in the worst case run code. The damage can spread past the vulnerable component into others.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade Dell PowerStore 500T to 5.1.0.0-2798105 or later or later. Other affected products have their own fixed versions on this page.
- Segment the networks that can reach it.
Description from NVD
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.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Native code: operating systems, browsers and firmware. The flaw sits wherever native code reads untrusted data.
- Network appliances and media or file parsers. The flaw sits wherever native code reads untrusted data.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- Isolation between components. The impact crosses out of the vulnerable component into others it should be isolated from.
- Wherever native code reads untrusted data. An attacker who crosses it can crash the process, read memory, or in the worst case run code.
Questions to answer about your own systems
- Where does Dell PowerStore 500T run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
