CVE-2025-23099
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 1480 and 2400. The lack of a length check leads to out-of-bounds writes.
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 confidenceBuffer overflow vulnerability in Samsung Exynos 1480 and 2400 mobile processors caused by missing length validation, allowing out-of-bounds memory writes that could enable arbitrary code execution or system compromise.

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 processor modelCheck the device specifications or use system information commands (e.g., 'getprop' on Android, or check /proc/cpuinfo) to determine if the chipset is Exynos 1480 or Exynos 2400Affected if The device uses an Exynos 1480 or Exynos 2400 processor
-
Check the baseband or modem firmware versionUse Android system commands such as 'getprop gsm.version.baseband' or check the modem firmware version through the device's about phone settings or diagnostic menusAffected if The installed baseband/modem firmware version is any version (all versions are affected according to the advisory)
-
Verify the Android security patch levelCheck the Android security patch level via Settings > About Phone > Security Patch Level, or use 'getprop ro.build.version.security_patch'Affected if The security patch level is earlier than the vendor release that addresses this vulnerability (once available)
-
Check for vendor-specific firmware updatesCheck for system updates through Settings > Software Update, or review Samsung's security bulletins for the patch release date addressing CVE-2025-23099Affected if No vendor firmware update addressing this CVE has been applied
The device is affected if it contains an Exynos 1480 or Exynos 2400 processor and is running firmware versions that have not been patched for this buffer overflow vulnerability.
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 firmware/security updates from Samsung once available; monitor Android security patch bulletins for affected devices; consider network-based controls to reduce attack surface until patches are deployed.
