Why this priority: Medium severity, with no exploitation signal.
Published · Updated · NVD status: Received
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 from the same local network segment, without an account, and nobody has to click anything. Success also depends on conditions the attacker does not fully control.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. 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. EPSS estimates a 0.18% chance of exploitation activity in the next 30 days, higher than 7% of scored CVEs.
What to do
- No fixed version is listed yet. Find every place STMicroelectronics st-mems-android-linux-sensors-hal runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- Segment the networks that can reach it.
Description from NVD
STMicroelectronics st-mems-android-linux-sensors-hal before 7bdf334 does not check whether the allowed number of channels is exceeded.
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
- Interfaces that accept external input. The flaw sits at the input boundary of the affected component.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- 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 STMicroelectronics st-mems-android-linux-sensors-hal 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?
