Multiple integer overflows in the JPEG engine drivers in the MSM camera driver for the Linux kernel 2.6.x and 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allow attackers to cause a denial of service (system crash) via a large number of commands in an ioctl call, related to (1) camera_v1/gemini/msm_gemini_sync.c, (2) camera_v2/gemini/msm_gemini_sync.c, (3) camera_v2/jpeg_10/msm_jpeg_sync.c, (4) gemini/msm_gemini_sync.c, (5) jpeg_10/msm_jpeg_sync.c, and (6) mercury/msm_mercury_sync.c.

Security readout for executives and security teams

Plain-English summary

CVE-2013-4736 is a legacy Qualcomm MSM Android kernel camera driver issue. Malformed or excessive JPEG engine commands through an ioctl call can trigger integer overflows and crash the system. The public bundle does not show code execution, data theft, or active exploitation.

Executive priority

Treat this as a legacy device stability risk. It is not shown as actively exploited, but unpatched affected devices may be crashable and unsuitable for critical operational roles without vendor-confirmed fixes.

Technical view

Multiple integer overflows affect MSM camera JPEG engine driver files in Linux kernel 2.6.x and 3.x QuIC Android contributions for MSM devices. The described impact is denial of service through a large command count in an ioctl call, involving gemini, jpeg_10, and mercury sync driver paths.

Likely exposure

Exposure is most plausible on older Android or embedded MSM device builds that incorporated the listed QuIC camera JPEG engine drivers. The bundle does not provide exact OEM models, patched versions, CPEs, or deployment prevalence.

Exploitation context

The source bundle does not cite KEV listing or in-the-wild exploitation. The known attack context is triggering a system crash through the vulnerable camera JPEG driver interface; no public source here supports privilege escalation or remote exploitation.

Researcher notes

The evidence is sparse: no CVSS, CWE, CPE, fixed version, or exploit status is provided. Analysis should stay bounded to integer overflow denial of service in specified MSM camera JPEG driver files.

Mitigation direction

  • Check OEM, Qualcomm, or CodeAurora guidance for CVE-2013-4736 remediation details.
  • Apply available firmware or kernel updates that address the vulnerable MSM camera drivers.
  • Inventory legacy MSM Android devices and prioritize unsupported devices for replacement or isolation.
  • Avoid claiming remediation complete without confirming the shipped kernel contains the fixed driver code.

Validation and detection

  • Identify devices or kernels using the listed MSM camera JPEG driver source paths.
  • Confirm kernel version lineage and whether QuIC MSM Android camera contributions were included.
  • Check vendor firmware release notes for CVE-2013-4736 or related camera driver fixes.
  • Verify patched source or binaries through vendor documentation or internal build records.
