CVE-2024-53026
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 · uneditedInformation disclosure when an invalid RTCP packet is received during a VoLTE/VoWiFi IMS call.
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 vulnerability in VoLTE/VoWiFi IMS call handling allows information disclosure when invalid or malformed RTCP (Real-time Transport Control Protocol) packets are processed during an active IMS call. The improper validation of RTCP packet structures enables an attacker to potentially expose sensitive call metadata or session information.

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 Qualcomm firmware componentCheck the device or system information to determine if any of the following Qualcomm components are present: Apq8017, Apq8064au, Aqt1000, Fastconnect 6200, Fastconnect 6700, Qcm6125, Qcm6490, or Qcm8550. This can be done via system firmware logs, modem diagnostic information, or by querying the baseband/modem version through AT commands or diagnostic tools.Affected if The device uses any of the listed Qualcomm firmware components (Apq8017, Apq8064au, Aqt1000, Fastconnect 6200, Fastconnect 6700, Qcm6125, Qcm6490, or Qcm8550)
-
Verify if VoLTE or VoWiFi is enabledCheck the device mobile network settings or IMS configuration. On Android devices, this can be found under Settings > Mobile Network > VoLTE/VoWiFi. On enterprise or infrastructure devices, check the IMS service configuration or VoLTE/VoWiFi daemon status.Affected if VoLTE (Voice over LTE) or VoWiFi (Voice over WiFi) is enabled on the device
-
Confirm IMS functionality is activeVerify that IMS (IP Multimedia Subsystem) is registered and active. This can be checked through modem logs, IMS registration status, or by inspecting the active IMS sessions via diagnostic interfaces such as QXDM, QPST, or vendor-specific OSS tools.Affected if The device has active IMS registration or ongoing IMS calls
-
Monitor RTCP packet handling during active callsCapture and inspect network traffic during an active VoLTE or VoWiFi call using packet capture tools (such as Wireshark or tcpdump). Look for RTCP packets being processed by the IMS stack. The vulnerability triggers when malformed RTCP packets are received during an active call session.Affected if The device processes RTCP packets during active IMS/VoLTE/VoWiFi calls
A device is affected if it uses any of the listed Qualcomm firmware components AND has VoLTE/VoWiFi/IMS enabled, as the vulnerability triggers during RTCP packet processing in active call sessions.

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 IMS/VoLTE/VoWiFi infrastructure components and implement network-level filtering to reject invalid RTCP packets at the edge.
