CVE-2025-52512
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 in Samsung Mobile Processor Exynos 2400, 1580, 2500. A race condition in the HTS driver results in out-of-bounds memory access, leading to a denial of service.
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 confidenceA race condition in the HTS (Hardware Thermal Sensor) driver for Samsung Exynos 2400, 1580, and 2500 mobile processors allows concurrent access to shared memory structures without proper synchronization, resulting in out-of-bounds memory access that can crash the device or cause a denial of service.

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 the mobile device processorCheck the device settings or system information to determine the processor model. On Android, this is typically found under Settings > About Phone > Model/MUA or using a system info app.Affected if The device uses a Samsung Exynos 1580, 2400, or 2500 processor
-
Confirm the Exynos variantVerify the exact Exynos model number through device diagnostic tools, bootloader information, or manufacturer specifications for your specific device model.Affected if The processor is specifically an Exynos 1580, Exynos 2400, or Exynos 2500
-
Check for available firmware/security updatesCheck for system updates in the device settings (Settings > System > Software Update or Settings > About Phone > Software Update). Look for any Samsung security patches or firmware updates.Affected if The device firmware has not been updated to address this vulnerability - note that all currently available firmware versions for these processors are affected
-
Monitor for thermal management anomaliesObserve the device for unusual thermal behavior, unexpected shutdowns, or thermal warning messages during normal use. The vulnerability can cause device crashes or denial of service through thermal sensor driver issues.Affected if The device exhibits repeated thermal warnings, unexpected reboots, or crashes particularly under normal thermal conditions
If the device contains a Samsung Exynos 1580, 2400, or 2500 processor and has not received a vendor-specific security patch for this vulnerability, the environment is affected by this race condition in the HTS driver.

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 Samsung firmware/security updates for affected devices. Until the vendor patch is available, monitor for unusual device behavior and consider restricting use of thermal-management-intensive applications on unpatched devices.
