CVE-2016-11030
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 · uneditedAn issue was discovered on Samsung mobile devices with KK(4.4), L(5.0/5.1), and M(6.0) (with Hrm sensor support) software. The sysfs of the MAX86902 sensor driver does not prevent concurrent access, leading to a race condition and resultant heap-based buffer overflow. The Samsung ID is SVE-2016-7341 (December 2016).
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 · high confidenceThe MAX86902 heart rate sensor driver's sysfs interface lacks proper synchronization primitives, allowing concurrent access that triggers a race condition. This race leads to a heap-based buffer overflow when multiple threads access the sensor's sysfs entries simultaneously on affected Samsung devices running Android KK, L, or M with Hrm sensor support.

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.
-
Check Android versionGo to Settings > About Phone and verify the Android version is exactly 4.4, 5.0, 5.1, or 6.0Affected if Android version matches one of these exact versions (4.4, 5.0, 5.1, or 6.0)
-
Verify device manufacturerCheck the device manufacturer is Samsung as the vulnerability specifically affects Samsung devicesAffected if The device is manufactured by Samsung
-
Confirm MAX86902 sensor presenceInspect system logs or /sys/class/sensors/ entries for the presence of a MAX86902 heart rate sensor deviceAffected if A MAX86902 heart rate sensor is present on the device
-
Check HRM sensor support statusExamine /sys/class/sensors/ or the sensor HAL configuration to determine if the HRM (heart rate monitor) sensor support is enabled and exposed via sysfsAffected if HRM sensor support is enabled and accessible through sysfs interface
A device is affected if it is a Samsung device running Android 4.4, 5.0, 5.1, or 6.0 with a MAX86902 heart rate sensor and HRM sensor support enabled via sysfs.

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 the Samsung firmware update containing the SVE-2016-7341 patch, which adds proper locking to the MAX86902 sysfs handlers to prevent concurrent access and eliminate the race condition.
