CVE-2024-43053
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 · uneditedMemory corruption while invoking IOCTL calls from user space to read WLAN target diagnostic information.
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 confidenceMemory corruption vulnerability in WLAN driver IOCTL handler allows local attackers to trigger improper memory operations when processing user-space requests for WLAN diagnostic information. The vulnerability stems from insufficient validation of IOCTL input from user space, potentially enabling 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 Qualcomm wireless hardware presentCheck system hardware inventory or device manager for Qualcomm Fastconnect adapters (6700, 6900, 7800) or QCA/QCC wireless modules (Qca2062, Qca2064, Qca2065, Qca2066, Qcc2073)Affected if Any of the listed Qualcomm wireless adapters are installed on the system
-
Retrieve WLAN firmware versionUse system information utilities (such as 'wmic path win32_networkadapter get name,driverversion' on Windows or 'lspci -v' or manufacturer tools on Linux) to query the installed firmware version of the Qualcomm wireless adapterAffected if The installed firmware version falls within the affected product list (all versions of Fastconnect 6700/6900/7800, Qca2062/2064/2065/2066, Qcc2073)
-
Check WLAN diagnostic IOCTL interface exposureInspect system logs for any unusual or unauthorized access to WLAN diagnostic IOCTL handlers; verify if user-space applications have the ability to send IOCTL requests to the WLAN driverAffected if The IOCTL handler for WLAN diagnostic information is exposed to user space without proper access controls
-
Monitor for abnormal IOCTL request patternsReview network monitoring tools, driver logs, or endpoint detection logs for suspicious IOCTL calls targeting the WLAN driver diagnostic interface, especially from untrusted user processesAffected if Unexpected or anomalous IOCTL requests to the WLAN driver diagnostic handler are observed
A system is affected if it contains any of the listed Qualcomm wireless adapters (Fastconnect 6700/6900/7800 or QCA/QCC variants) with unpatched firmware, where the WLAN diagnostic IOCTL interface is accessible to user-space processes.

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-specific patches for affected WLAN drivers; consider network access controls to limit exposure and monitor for exploitation attempts.
