CVE-2015-4167

MEDIUMCVSS v2 · 4.74.7—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 4.7 — v2 rates that MEDIUM (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:L/AC:M/Au:N/C:N/I:N/A:C. CVSS v2 is an older, coarser metric than v3.1/v4.0 (no Scope, no User Interaction, no Attack Requirements), so it is not directly comparable to a v3 or v4 score. NVD has never re-scored this record under v3. EPSS predicts 0.4% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

A fix is available — apply it.

The udf_read_inode function in fs/udf/inode.c in the Linux kernel before 3.19.1 does not validate certain length values, which allows local users to cause a denial of service (incorrect data representation or integer overflow, and OOPS) via a crafted UDF filesystem.

EG Risk 26/100CISA SSVC

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact unknown (not published for this CVE). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.

Frequently asked(4)

What is CVE-2015-4167?
CVE-2015-4167 is a medium vulnerability published on August 5, 2015. The udfreadinode function in fs/udf/inode.c in the Linux kernel before 3.19.1 does not validate certain length values, which allows local users to cause a denial of service (incorrect data representation or integer overflow, and OOPS) via a crafted UDF filesystem.
When was CVE-2015-4167 disclosed?
CVE-2015-4167 was first published on August 5, 2015, with the most recent update on May 6, 2026. EchelonGraph re-ingests CVE updates from NVD on a 2-hour cycle, so this page reflects the latest published state.
Is CVE-2015-4167 actively exploited?
CVE-2015-4167 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.4% probability of exploitation in the next 30 days (35th percentile of EPSS-scored CVEs).
How do I remediate CVE-2015-4167?
A fix for CVE-2015-4167 is available: update to the fixed version the vendor names in its advisory.
