CVE-2025-54601
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 the Wi-Fi driver in Samsung Mobile Processor amd Wearable Processor Exynos 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. Improper synchronization on a global variable leads to a double free. An attacker can trigger a race condition by invoking an ioctl function concurrently from multiple threads.
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 Samsung Exynos Wi-Fi driver occurs when multiple threads concurrently invoke ioctl functions. Due to improper synchronization on a global variable, the same memory can be freed twice (double-free), leading to memory corruption that could be exploited for local privilege escalation or 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 Exynos processor modelCheck /proc/cpuinfo or device tree (DT) on the device to determine the exact Exynos chipset (e.g., 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, W1000)Affected if The processor is any of: Exynos 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, or W1000
-
Confirm Wi-Fi driver is loadedCheck if the Wi-Fi driver module for the Exynos Wi-Fi subsystem is loaded (lsmod | grep -i exynos or check wlan driver status in /sys/kernel/debug)Affected if The Exynos Wi-Fi driver module is active and running
-
Check Wi-Fi firmware versionRead the Wi-Fi firmware version from the driver debug interface or firmware file (e.g., check /sys/class/wlan0/.... or inspect firmware binary files in /lib/firmware)Affected if Any firmware version is present on an affected Exynos model (all versions are vulnerable)
-
Determine if concurrent ioctl access is possibleAudit the system's threading model and Wi-Fi daemon configuration to see if multiple threads/processes can invoke Wi-Fi ioctl calls simultaneously (review Wi-Fi manager service and concurrent connection settings)Affected if Multiple threads or processes can invoke Wi-Fi ioctl functions concurrently on the device
A device is affected if it uses any of the listed Exynos processors (980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, W1000) with an active Wi-Fi driver, regardless of firmware version, and if concurrent ioctl access to the Wi-Fi driver is possible.

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 dataThe vulnerability requires driver-level remediation: add proper mutex or spinlock synchronization around the global variable accessed by ioctl to prevent concurrent access. Samsung will need to release a firmware or driver patch for affected devices.
