The CONFIG_STRICT_MEMORY_RWX implementation for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not properly consider certain memory sections, which makes it easier for attackers to bypass intended access restrictions by leveraging the presence of RWX memory at a fixed location.

Security readout for executives and security teams

Plain-English summary

This CVE describes a weakness in a Linux kernel memory-protection feature used in Qualcomm Innovation Center Android MSM kernel contributions. Some memory could remain readable, writable, and executable at a predictable location, making attacks easier after another foothold. The source bundle does not name exact device models, fixes, or active exploitation.

Executive priority

Prioritize this for legacy mobile, embedded, or Qualcomm MSM-based fleets. For typical modern IT environments, urgency is unclear because affected products and fixes are not specified. The main business task is exposure discovery and lifecycle risk management.

Technical view

The issue is in CONFIG_STRICT_MEMORY_RWX handling for Linux kernel 3.x in QuIC Android MSM contributions. Certain memory sections were not properly considered, leaving RWX memory at a fixed location and weakening intended execute/write restrictions. Available metadata does not provide CVSS, CWE, affected version ranges, or remediation details.

Likely exposure

Most likely exposure is legacy Android or embedded products using Linux kernel 3.x derived from Qualcomm Innovation Center MSM Android contributions. The provided sources do not identify specific vendors, models, firmware builds, or CPEs, so exposure requires local asset and firmware validation.

Exploitation context

The sources describe an attacker advantage for bypassing memory access restrictions, not a standalone remote compromise. There is no KEV listing and no cited evidence of active exploitation in the provided bundle. Treat exploitation status as unconfirmed.

Researcher notes

Evidence is sparse. The CVE record identifies a kernel hardening bypass condition involving fixed-location RWX memory, but does not provide affected CPEs, scoring, or patch details. Avoid broad product claims without firmware-level confirmation.

Mitigation direction

  • Inventory Android/MSM devices and products running Linux kernel 3.x firmware.
  • Map firmware lineage to Qualcomm Innovation Center Android MSM kernel contributions.
  • Check vendor or OEM guidance for CVE-2013-4737 before assuming a fix.
  • Apply supported firmware or kernel updates only where vendor guidance confirms coverage.
  • Isolate, restrict, or replace unsupported devices confirmed to use affected kernel code.

Validation and detection

  • Confirm kernel version and build provenance for suspected Android/MSM devices.
  • Check whether CONFIG_STRICT_MEMORY_RWX is enabled in the affected kernel configuration.
  • Review vendor patch notes for explicit CVE-2013-4737 coverage.
  • Document firmware version, kernel source lineage, and update availability.
  • Validate compensating controls for unsupported devices in sensitive environments.
