CVE-2026-49014: OSGeo Gdal

High severity, CVSS 7.8. EPSS: 0.1% chance of exploitation in the next 30 days.

In GDAL 3.1.0 through 3.13.0, scanForGeometryContainers in the netCDF driver allows code execution via a stack-based buffer overflow. It reads a geometry attribute into a fixed-size stack buffer without validating the attribute length. The attacker embeds the exploit as an oversized geometry attribute in a crafted NetCDF file. This achieves arbitrary code execution on the server running GDAL. This is in frmts/netcdf/netcdfsg.cpp.

Affected products

• OSGeo Gdal: from 3.1.0, up to and including 3.13.0
