CVE-2026-113604 — Ghidra 10.2 through 12.1.4 Denial of Service via ELF Loader Extended Header Counts

Ghidra 10.2 through 12.1.4 contains a denial of service vulnerability in the ELF loader's ElfHeader class that allocates arrays sized by unvalidated extended section and program header counts. Attackers can supply a crafted 128-byte ELF file that triggers an OutOfMemoryError during load-spec discovery at import or in headless analysis pipelines.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

EPSS FIRST

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Nationalsecurityagency Ghidra).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
Search available logs for exploit probes, errors and authentication anomalies.
