Summary

CVE-2026-8086 is a low-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Osgeo Gdal. Its CVSS base score is 1.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 15th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly addresses the publicly disclosed flaw by requiring prompt application of the vendor patch that fixes the heap buffer overflow in SWnentries.

prevent

Enforces validation of untrusted input (DimensionName) before it reaches the vulnerable HDF-EOS parsing code, blocking the overflow condition.

prevent

Limits the impact of a successful local exploit by ensuring the GDAL-using process runs with only the privileges required for its task.

detects

Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.

prevents

Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.

prevents

Application security requirements can specify memory-safety rules, but do not prescribe implementation details.

prevents

Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.

prevents

Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.

none

Change management ensures controlled deployment of fixes for discovered heap-overflow vulnerabilities.
