CVE-2024-23369
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 when invalid length is provided from HLOS for FRS/UDS request/response buffers.
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 memory corruption vulnerability exists where invalid length values provided from the High-Level Operating System (HLOS) for FRS/UDS diagnostic request and response buffers are not properly validated before use. This allows an attacker to trigger buffer overflows or out-of-bounds memory access by supplying malformed length parameters, leading to potential code execution or system compromise.

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 chipset modelCheck the device specifications or system information to determine if the platform is one of the affected models: Snapdragon 888+ 5g (sm8350), Snapdragon 865+ 5g (sm8250), WSA8845H, WSA8845, WSA8840, WSA8835, WSA8832, or WSA8830Affected if The device uses any of the listed Qualcomm chipsets or firmware platforms
-
Confirm diagnostic services are exposedDetermine if FRS (Fast Re-start) or UDS (Unified Diagnostic Services) diagnostic interfaces are enabled and accessible on the device, typically through service documentation or network exposure scanningAffected if FRS or UDS diagnostic services are enabled and reachable from an attacker-controlled interface
-
Verify HLOS-to-firmware communication pathInspect the diagnostic communication pathway between the High-Level Operating System and the firmware to confirm that buffer length parameters can be supplied from the HLOSAffected if The device architecture allows HLOS-supplied length parameters to reach the FRS/UDS buffer handling code in firmware
-
Check for exploitation indicatorsReview firmware or system logs for signs of anomalous diagnostic requests, memory corruption events, or unexpected service behavior that may indicate buffer overflow exploitationAffected if Any anomalous logs or system behavior related to diagnostic buffer operations are observed
-
Assess attack surfaceEvaluate whether the diagnostic interface is exposed to untrusted inputs, such as over network protocols, USB debugging, or other external interfacesAffected if The FRS/UDS diagnostic interface accepts input from untrusted or external sources without sufficient validation
A device is affected if it uses any of the listed Qualcomm chipsets and exposes FRS/UDS diagnostic services to inputs that can supply malformed length parameters from the HLOS.

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 dataImplement rigorous input validation on all length parameters received from HLOS for FRS/UDS buffers, ensuring lengths are within expected bounds before any buffer operations. Apply secure coding practices including bounds checking and use of safe memory copy functions.
