CVE-2023-32805
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 power, there is a possible out of bounds write due to an insecure default value. This could lead to local escalation of privilege with System execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS08102892; Issue ID: ALPS08102892.
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 an out-of-bounds write vulnerability in the power management subsystem of MediaTek ALPS (Android Linux Platform). The flaw stems from an insecure default value that allows writing beyond allocated buffer boundaries. A local attacker with System-level execution privileges could potentially escalate privileges, though 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.
-
Check Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via adb shellAffected if Version is exactly 11.0 or 12.0
-
Verify MediaTek chipsetRun 'getprop ro.hardware' or 'getprop ro.chipset' via adb shell, or check /proc/cpuinfo for MediaTek processor infoAffected if Device uses a MediaTek SoC/processor
-
Confirm power management subsystem is activeCheck for the presence of Mediatek power management kernel modules: look for files containing 'mtk_pmic' or similar in /vendor/lib/modules/ or check 'lsmod' output for power management related modulesAffected if MediaTek power management kernel modules are loaded and active
-
Identify vulnerable power management componentReview /sys/kernel/debug/vcpu or /sys/power/ state files, or check /vendor/firmware/ for power management firmware filesAffected if Power management component with MediaTek ALPS firmware is present
-
Check system privilegesVerify current process has System-level privileges using 'id' command or check process capabilities via 'cat /proc/<pid>/status'Affected if Exploitation requires System-level execution privileges, which are typically held by system_server and certain system services
You are affected only if your device runs Android version 11.0 or 12.0 on a MediaTek chipset with the vulnerable power management subsystem enabled, and an attacker with System-level privileges can trigger the out-of-bounds write via the insecure default buffer value.

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 patch ALPS08102892 which corrects the insecure default value in the power management component. This is a MediaTek platform vulnerability requiring a system firmware/software update.
