Security readout for executives and security teams

CVE-2013-6392 is a local information disclosure flaw in the Linux Genlock driver used in Qualcomm Android MSM kernel contributions. A local user could receive uninitialized kernel stack data through a Genlock ioctl. This is primarily a confidentiality issue, not remote compromise based on the provided sources. Exposure is most likely in older Android/MSM-derived Linux kernel 3.x builds that include the Genlock driver. General Linux systems without this Qualcomm Genlock code path are not shown as affected by the supplied sources. Treat as a targeted legacy-platform risk. Prioritize if the organization manages older Qualcomm Android devices or custom MSM-based products. For ordinary modern server fleets, the provided evidence does not indicate broad exposure. Mitigation focus: Check vendor guidance for affected Android/MSM kernel branches.; Apply the referenced Genlock initialization fix or a vendor-equivalent kernel update.; Retire unsupported devices or kernels that cannot receive security fixes..
