CVE-2022-32624
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 throttling, there is a possible out of bounds write due to an incorrect calculation of buffer size. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07405923; Issue ID: ALPS07405923.
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 confidenceThis is a local privilege escalation vulnerability in MediaTek's throttling component. The vulnerability is caused by an incorrect buffer size calculation that leads to an out-of-bounds write, potentially allowing an attacker with System-level privileges to escalate to higher privileges. No user interaction is required for exploitation.

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.
-
Confirm Android version is affectedCheck the device Android version (Settings > About Phone > Android version). This vulnerability affects only Android 11.0 and 12.0 exactly.Affected if The device is running Android 11.0 or Android 12.0
-
Identify chipset vendorCheck if the device uses a MediaTek chipset. This can be done via device info settings, /proc/cpuinfo, or by checking the kernel config for MediaTek components.Affected if The device uses a MediaTek chipset
-
Verify throttling component presenceLocate the MediaTek throttling driver on the device. This is typically found in the kernel module path or as part of the thermal management subsystem. Check for files or modules related to MediaTek throttling (often under /vendor or /system).Affected if The MediaTek throttling component is present on the device
-
Check throttling driver patch levelInspect the throttling driver binary or its version information. Compare the build/patch date or version string against the MediaTek patch ALPS07405923 which contains the fix for the buffer size calculation vulnerability.Affected if The throttling driver version predates patch ALPS07405923 or the patch is not applied
A device is affected if it runs Android 11.0 or 12.0, uses a MediaTek chipset, has the throttling component present, and does not have the ALPS07405923 patch applied to the throttling driver.

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 the MediaTek patch ALPS07405923 through device firmware/OTA updates from the device manufacturer. This is a vendor-supplied patch for the throttling driver that corrects the buffer size calculation.
