CVE-2026-33972Samsung Semiconductor Exynos 1080 unchecked quantity
CVE-2026-33972 is a unchecked quantity in Samsung Semiconductor Exynos 1080, rated critical (9.8 on CVSS 3.1).
Why this priority: Critical, and reachable over the network without an account.
Published · Updated · NVD status: Deferred
What it is
A count or size from input is not checked before it is used.
How it is reached
An attacker can exploit it over the network, without an account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker drive the component into behaviour its authors did not intend.
Is it being exploited?
There is no public report of exploitation yet. It can be exploited automatically, at scale. EPSS estimates a 0.15% chance of exploitation activity in the next 30 days, higher than 4% of scored CVEs.
What to do
- No fixed version is listed yet. Find every place Samsung Semiconductor Exynos 1080 runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- While there is no fix, keep it off the internet or behind a VPN, allowlist or authenticating proxy.
Description from NVD
In the Exynos modem's IMS stack, Out of Bound access occurs due to improper validation.
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
- Network edge devices: VPNs, firewalls, routers and gateways. They sit between the internet and internal networks, so a flaw in one is often the first step into everything behind it.
- Interfaces that accept external input. The flaw sits at the input boundary of the affected component.
Trust boundaries in play
- Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
- At the input boundary of the affected component. An attacker who crosses it can drive the component into behaviour its authors did not intend.
Questions to answer about your own systems
- Where does Samsung Semiconductor Exynos 1080 run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
