CVE-2024-29756
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 · uneditedIn afe_callback of q6afe.c, there is a possible out of bounds write due to a buffer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
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 buffer overflow vulnerability exists in the afe_callback function within the q6afe.c Qualcomm AFE (Audio Front End) driver. The out-of-bounds write allows a local attacker to escalate privileges to root without requiring any additional execution privileges or user interaction.

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 if device uses Qualcomm chipsetCheck /sys/bus/platform/devices for qcom-related audio devices, or check /proc/cpuinfo for 'Qualcomm' or 'Snapdragon' mentions, or use 'getprop ro.hardware' to check the hardware propertyAffected if Device does not use Qualcomm hardware - the driver vulnerability only applies to Qualcomm AFE implementations
-
Confirm q6afe driver is presentCheck /proc/modules for 'q6afe' or 'q6afe_dlkm' entries, or check /sys/module for 'q6afe' directory existenceAffected if q6afe module/driver is not loaded or present - the vulnerability only exists when this specific driver is in use
-
Check kernel build fingerprint for patch levelRun 'getprop ro.build.version.security_patch' to get the Android security patch level, and 'getprop ro.kernel.version' for kernel version. Compare against any vendor patch announcements for CVE-2024-29756Affected if Security patch level is older than the vendor release date for the CVE-2024-29756 fix for your specific device model
-
Verify Audio Front End driver versionIf q6afe is present, check /sys/module/q6afe/version or examine /sys/bus/platform/drivers/q6afe/*/version to identify the driver build dateAffected if Driver version predates the CVE fix release from Qualcomm/OEM for your specific chipset generation
User is affected if the device runs on Qualcomm hardware with the q6afe driver loaded and the Android security patch level predates the vendor-specific fix for CVE-2024-29756

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/security patch from Qualcomm for affected devices. This is a kernel-space driver vulnerability requiring OEM//vendor firmware update rather than application-level remediation.
