CVE-2015-8593
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn all Qualcomm products with Android releases from CAF using the Linux kernel, a buffer overflow vulnerability exists in 1x call processing.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA buffer overflow vulnerability exists in the 1x (CDMA 1xRTT) call processing component within Qualcomm's Android firmware releases from CAF using the Linux kernel. The vulnerability allows potential remote code execution or denial of service via malformed 1x call signaling.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify your baseband processor typeGo to Settings > About Phone > Baseband version or use 'getprop' command via ADB to check the baseband version string (e.g., 'getprop gsm.version.baseband')Affected if The device uses a Qualcomm-based baseband processor (indicated by Qualcomm in the version string or CAF/MSM references)
-
Confirm CDMA 1xRTT capability is presentCheck if the device supports CDMA by looking at Settings > About Phone > MEID or ESN, or check network type indicators when connected to a CDMA networkAffected if The device has CDMA 1xRTT radio capability enabled and can connect to CDMA networks
-
Determine the baseband firmware ageCheck the baseband version string and compare it against the most recent available from your device OEM/carrier. On Android, use Settings > About Phone > Build number or 'getprop' to identify when the last update was appliedAffected if The baseband firmware has not been updated from the original Android version shipped with the device, indicating it may contain the unpatched vulnerable code
-
Inspect kernel logs for 1x call errorsUse 'logcat -b radio' or check /proc/kmsg for 1xRTT call processing messages. Look for crashes or anomalies in the '1x' or 'CDMA' radio subsystemAffected if Repeated crashes or unexpected behavior in 1x call signaling are observed, which may indicate exploitation attempts
You are affected if your device has a Qualcomm baseband with CDMA 1xRTT capability and the baseband firmware has not been updated to include the vendor patch for this flaw.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware/baseband updates from Qualcomm and device manufacturers. As this is a baseband/processor-level flaw in the radio stack, users must obtain patched images from their device OEM or carrier.
