Security readout for executives and security teams
Plain-English summary
This CVE concerns radare2's WebAssembly disassembly code handling a crafted WASM file. The supplied record does not provide a CVSS score, affected versions, or a precise business impact. Treat it as a tooling risk for environments that analyze untrusted WASM, not as evidence of broad enterprise compromise.
Executive priority
Handle as a moderate operational hygiene item unless radare2 processes untrusted WASM in automated pipelines. Business urgency rises for malware analysis, CI, reverse engineering, or security tooling environments where crafted files are routinely opened.
Technical view
The issue is tied to wasm_dis() in libr/asm/arch/wasm/wasm.c, with upstream radare2 issue and commit references. The CVE text says a crafted WASM file can trigger an unspecified impact. The supplied sources do not identify affected versions, confirmed impact class, or complete remediation instructions.
Likely exposure
Exposure is most likely where radare2 or tools embedding its WASM disassembler process untrusted or attacker-supplied WASM files. The source bundle lists affected vendor and product as n/a, so exact asset matching requires local version and dependency validation.
Exploitation context
The supplied bundle does not cite active exploitation, public weaponization, or KEV inclusion. The threat scenario is malicious file parsing: a crafted WASM file reaches vulnerable disassembly logic during analysis or automated processing.
Researcher notes
The public record is sparse: no CVSS, CWE, affected versions, or precise impact are supplied. Analysis should stay anchored to the radare2 issue, commit, and local build provenance. Do not assume remote code execution or active exploitation from this bundle.
Mitigation direction
- Check radare2 guidance and the referenced upstream commit.
- Update radare2 to a version containing the upstream fix.
- Avoid processing untrusted WASM files with unverified vulnerable tooling.
- Run WASM analysis tools in a sandboxed, low-privilege environment.
- Monitor vendor and distribution advisories for version-specific remediation.
Validation and detection
- Inventory radare2 installations and embedded radare2 libraries.
- Confirm whether installed builds include the referenced upstream commit.
- Identify workflows that parse untrusted or external WASM files.
- Review crash reports from WASM disassembly or analysis jobs.
- Document any compensating sandboxing or isolation controls.
