CVE-2025-49495
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 WiFi driver in Samsung Mobile Processor Exynos 1380, 1480, 2400, 1580. Mishandling of an NL80211 vendor command leads to a buffer overflow.
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 WiFi drivers (1380, 1480, 2400, 1580) due to improper handling of NL80211 vendor commands. This could allow remote code execution or denial of service via malicious wireless commands.

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 chipset modelCheck the system hardware information or WiFi adapter chipset specification to determine if the device uses an Exynos 1380, 1480, 1580, or 2400 processor. This can be done via lspci, lsusb, or device specifications.Affected if The device incorporates any of the four affected Exynos variants (1380, 1480, 1580, 2400)
-
Retrieve the WiFi firmware versionQuery the WiFi driver or firmware management interface to obtain the installed firmware version for the Exynos WiFi module. Use vendor-specific tools or system information utilities that report wireless firmware versions.Affected if The firmware version matches one of the affected Exynos models (1380, 1480, 1580, or 2400) - all versions of these firmware variants are affected
-
Confirm WiFi functionality is enabledCheck if the wireless interface is active and the Exynos WiFi driver is loaded. Inspect network interface status and driver module listing.Affected if WiFi is enabled and the Exynos wireless driver is actively running with any of the affected firmware versions
-
Verify NL80211 vendor command supportInspect the wireless driver configuration or netlink interface to confirm support for NL80211 vendor-specific commands is present. This is typically exposed through the cfg80211 kernel module or similar wireless subsystem.Affected if The driver exposes NL80211 vendor command interface and processes wireless configuration inputs through it
A device is affected if it runs any version of firmware on an Exynos 1380, 1480, 1580, or 2400 WiFi chipset with the vendor command interface enabled.

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/patch to address the NL80211 command handler bounds checking. Users should update device firmware when patches become available.
