CVE-2024-56190
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 · uneditedIn wl_update_hidden_ap_ie() of wl_cfgscan.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
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 local privilege escalation vulnerability exists in the wl_update_hidden_ap_ie() function within wl_cfgscan.c (a wireless driver component). The function performs improper input validation when processing hidden AP Information Elements, leading to an out-of-bounds write condition. This allows a local attacker to potentially overwrite kernel memory and escalate privileges without requiring additional execution privileges or user interaction.

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.
-
Confirm system is AndroidCheck /system/build.prop for ro.build.fingerprint or run 'getprop ro.build.version.release' to verify the operating systemAffected if System is Google Android and the vulnerable wireless driver component is present
-
Identify wireless driver presenceSearch for wl_cfgscan.c or wl_cfgscan module in /system/lib/modules/ or /kernel/drivers/net/wireless/ directories, or run 'lsmod | grep wl' to list loaded wireless modulesAffected if The wl_cfgscan wireless driver component is loaded or present on the device
-
Check kernel version and patch levelRun 'uname -a' or check /proc/version to retrieve kernel version; compare against any vendor security bulletin patch datesAffected if Kernel version is unpatched for the CVE-2024-56190 vulnerability
-
Verify wireless interface statusRun 'ip link show' or 'iwconfig' to check if a wireless interface (typically wlan0) is present and activeAffected if Wireless interface is available and the vulnerable driver code path could be exercised
-
Check for hidden AP processing capabilityExamine wireless driver logs (dmesg | grep -i wl) or vendor-specific wireless daemon logs for hidden AP scanning functionalityAffected if Hidden AP scanning feature is enabled in the wireless driver configuration
A user is affected if running any version of Google Android with the wl_cfgscan wireless driver component present and wireless functionality enabled, since the affected products list covers all Android versions.

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 the vendor-provided security patch for the affected wireless driver (wl_cfgscan.c). This typically involves updating the kernel wireless driver package or firmware to a version containing the corrected input validation logic in the wl_update_hidden_ap_ie() function.
