CVE-2025-52908
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 and Wearable Processor Exynos 980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. Incorrect Handling of the NL80211 vendor command leads to a buffer overflow via a certain ioctl message, issue 1 of 2.
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 buffer overflow vulnerability exists in the Wi-Fi driver of multiple Samsung Exynos processors (980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, W1000). The vulnerability stems from incorrect handling of NL80211 vendor commands, allowing a specially crafted ioctl message to trigger a buffer overflow in the Wi-Fi firmware/driver stack.

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 in your deviceCheck your device specifications or system information to determine which Exynos processor (980, 850, 1380, 1480, 1580, W920, W930, or W1000) is present in the device. This is typically found in the device settings under 'About Phone' or in the product documentation.Affected if The device contains any of the following Exynos processors: 980, 850, 1380, 1480, 1580, W920, W930, or W1000.
-
Determine the Wi-Fi firmware versionAccess the Wi-Fi driver or firmware version through the device settings (usually under Settings > About Phone > Wi-Fi Information or through diagnostic menus), or use a system information app that displays Wi-Fi firmware details.Affected if The device uses one of the affected Exynos processors AND the Wi-Fi firmware is present (all versions of the listed firmware are affected).
-
Verify NL80211 vendor command supportInspect the Wi-Fi driver or kernel modules for NL80211 vendor command handling. This typically involves checking the kernel configuration for CONFIG_CFG80211 and vendor-specific ioctl handlers in the Wi-Fi driver modules.Affected if The Wi-Fi driver implements NL80211 vendor command handling (ioctl message processing for vendor-specific commands). This is the attack surface for the buffer overflow.
If your device contains an affected Exynos processor (980, 850, 1380, 1480, 1580, W920, W930, or W1000) and uses the stock Wi-Fi firmware/driver with NL80211 vendor command support, you are likely affected by this 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-supplied firmware updates from Samsung for affected Exynos processors. This is a firmware-level vulnerability requiring patches from the device manufacturer rather than application-level remediation.
