The regular-expression implementation in Google V8, as used in Google Chrome before 44.0.2403.89, mishandles interrupts, which allows remote attackers to cause a denial of service (application crash) via crafted JavaScript code, as demonstrated by an error in garbage collection during allocation of a stack-overflow exception message.

Analyst readout for executives and security teams

Plain-English summary

CVE-2015-5605 is a browser stability flaw in Google V8 used by older Google Chrome releases. A malicious web page could make Chrome crash, causing denial of service for the user. The provided sources support application crash impact, not data theft, privilege escalation, or code execution.

Executive priority

Treat this as a routine browser patching issue unless legacy browser versions remain in use. Business risk is disruption from browser crashes, not confirmed compromise. Patch validation is still important for exposed browsing environments.

Technical view

The V8 regular-expression engine mishandled interrupts in Chrome before 44.0.2403.89. The CVE describes a crash path involving garbage collection during allocation of a stack-overflow exception message. The documented security impact is remote denial of service through crafted JavaScript.

Likely exposure

Exposure is most likely on systems still running Google Chrome before 44.0.2403.89, or downstream Chromium/V8 packages addressed by vendor advisories. The bundle does not establish affected status for other V8 embedders.

Exploitation context

The CVE is not listed as KEV in the supplied bundle, and no cited source confirms active exploitation. The plausible attack path is visiting attacker-controlled or compromised web content that triggers a browser crash.

Researcher notes

Source evidence is limited to CVE text, Chromium/V8 references, a Chrome stable update, and Linux vendor advisories. No CVSS, CWE, KEV listing, or active exploitation evidence is provided in the bundle.

Mitigation direction

  • Upgrade Google Chrome to 44.0.2403.89 or later.
  • Apply relevant Red Hat or openSUSE Chromium package advisories where applicable.
  • Check current vendor guidance for any downstream V8-based products.
  • Prioritize managed browsers on shared kiosks, VDI, and operational workstations.

Validation and detection

  • Inventory Chrome and Chromium versions across endpoints.
  • Confirm no managed systems run Chrome earlier than 44.0.2403.89.
  • Review Linux package advisory status for affected distributions.
  • Check browser crash telemetry for repeated regex or V8-related crashes.
