CVE-2025-23096
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 1280, 2200, 1380, 1480, 2400. A Double Free in the mobile processor leads to privilege escalation.
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 double-free memory corruption vulnerability exists in Samsung Exynos mobile processors (1280, 2200, 1380, 1480, 2400). The flaw allows a local attacker to potentially gain elevated privileges through corrupting memory allocation metadata by freeing the same memory pointer twice, leading to arbitrary code execution at elevated privilege levels.

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 Exynos processor model in the deviceCheck the device specifications or system-on-chip (SoC) information to determine which Exynos processor is installed. On Android devices, this can be found in Settings > About Phone > SoC or through terminal commands like 'cat /proc/cpuinfo'. On other devices, consult the manufacturer documentation.Affected if The device uses an Exynos 1280, 2200, 1380, 1480, or 2400 processor.
-
Confirm the processor is in the affected listVerify the identified Exynos model matches one of the five affected processors: 1280, 2200, 1380, 1480, or 2400.Affected if The device contains any of these five Exynos processor models.
-
Check the firmware version of the Exynos processorAccess the baseband or modem firmware version through Android settings (Settings > About Phone > Baseband version) or via terminal commands such as 'getprop gsm.version.baseband' or 'AT+CGMR' for modem firmware.Affected if The firmware version present is an unpatched build; however, since all versions are listed as affected, any unpatched firmware version indicates vulnerability.
-
Verify vendor security patch statusCheck if the device manufacturer has applied security patches for this CVE. On Android, verify the Android Security Patch Level in Settings > About Phone > Android version. Samsung devices may also show specific kernel or trustzone firmware version information.Affected if The device security patch level is older than the vendor-supplied patch addressing CVE-2025-23096, or no patch has been applied.
A device is affected if it contains an Exynos 1280, 2200, 1380, 1480, or 2400 processor and does not have the vendor-supplied firmware/security patch for CVE-2025-23096 applied.

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/security patches from Samsung for affected devices. Since this is a processor-level vulnerability, no practical workarounds exist; organizations must update to patched firmware versions.
