Use-after-free vulnerability in the GetLoadTimes function in renderer/loadtimes_extension_bindings.cc in the Extensions implementation in Google Chrome before 47.0.2526.73 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that modifies a pointer used for reporting loadTimes data.
CVE-2015-6774
HIGHCVSS v2 · 7.57.5—
EchelonGraph scoreLOW confidence
This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 7.5 — v2 rates that HIGH (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:N/AC:L/Au:N/C:P/I:P/A:P. 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 1.5% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.
