CVE-2024-43058
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 processing IOCTL calls.
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 IOCTL handler allowing an attacker to corrupt memory via specially crafted IOCTL requests. The high CVSS score reflects the potential for privilege escalation and system compromise.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Check for Qualcomm Snapdragon 8 Gen 1 processorUse system information tools (e.g., 'lshw', 'dmidecode', or on Android: 'Settings > About Phone' or 'getprop ro.board.platform') to identify if the system contains a Snapdragon 8 Gen 1 Mobile PlatformAffected if The processor is Snapdragon 8 Gen 1 (SM8450 or SM8475)
-
Check for Qualcomm Fastconnect Wi-Fi adapterList network adapters or Wi-Fi drivers (e.g., 'lspci -v', 'lsusb -v', or check device manager). Look for Qualcomm Atheros or Qualcomm Fastconnect wireless adaptersAffected if A Fastconnect 6900 or Fastconnect 7800 Wi-Fi adapter is present in the system
-
Check for Qualcomm audio codec componentsList audio devices and drivers (e.g., 'pactl list', 'lsmod | grep -i wcd', or check sound card information). Look for Wcd9380, Wsa8830, or Wsa8835 codec driversAffected if Any of these Qualcomm audio codec drivers (Wcd9380, Wsa8830, Wsa8835) are loaded or present
-
Inspect IOCTL handler exposureCheck if the relevant device files exist in /dev or /sys (e.g., for wireless drivers: '/proc/net/wireless', 'iw list', or driver-specific device nodes). Verify IOCTL interfaces are accessible to user-spaceAffected if IOCTL interfaces for the Qualcomm components are accessible and exposed
-
Check firmware/driver versionsQuery the firmware or driver version through vendor tools, 'dmesg' logs, or system management interfaces. For Android: check 'Settings > About Phone > Baseband version' or use 'getprop'Affected if Any firmware or driver version is reported for the affected Qualcomm components (since all versions are vulnerable)
The system is affected if it contains any Qualcomm Fastconnect 6900/7800, Snapdragon 8 Gen 1, Wcd9380, Wsa8830, or Wsa8835 components, as all versions of these firmware are vulnerable to the IOCTL memory corruption flaw.

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 patches for affected drivers. Implement robust input validation and bounds checking in IOCTL handlers. Consider disabling unnecessary drivers or services that expose IOCTL interfaces to untrusted inputs.
