CVE-2021-30292
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 · uneditedPossible memory corruption due to lack of validation of client data used for memory allocation in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Wearables
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 Qualcomm Snapdragon chipsets caused by insufficient validation of client-supplied data before memory allocation operations. This could allow an attacker to manipulate allocation sizes or addresses, potentially leading to heap corruption, buffer overflows, or arbitrary code execution.

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 chipset modelOn Android devices, check /proc/cpuinfo or use a system info app to read the chipset identifier. On embedded devices, check dmesg, /proc/device-tree/model, or manufacturer hardware documentation.Affected if The chipset model matches any of the following: Apq8017, Apq8053, Apq8064au, Apq8096au, Aqt1000, Msm8917, Msm8953, or Msm8996au
-
Confirm firmware versionRead the firmware or baseband version from the device settings, /proc/version, or via AT commands on the modem interface (for mobile devices).Affected if Any firmware version is present on an affected chipset model (all versions are vulnerable).
-
Verify the device uses the vulnerable chipset firmwareCheck if the device actively uses Qualcomm modem/baseband firmware or other chipset components by monitoring baseband communications or checking system services that interface with the chipset.Affected if The device communicates with or utilizes any firmware component from the affected Qualcomm chipset line.
If the device contains any of the listed Qualcomm chipset models (Apq8017, Apq8053, Apq8064au, Apq8096au, Aqt1000, Msm8917, Msm8953, Msm8996au), it is affected regardless of firmware version since all versions contain the vulnerability.

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 firmware updates from Qualcomm or device manufacturers to patch the memory allocation validation flaw. Until patches are available, minimize attack surface by restricting untrusted network or user inputs from reaching affected chipset components.
