CVE-2024-20083
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 venc, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08810810 / ALPS08805789; Issue ID: MSV-1502.
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 · high confidenceThis is an out-of-bounds write vulnerability in the MediaTek video encoder (venc) component caused by a missing bounds check. An attacker with System-level access can exploit this to write data beyond allocated memory boundaries, potentially achieving arbitrary code execution and privilege escalation. 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.
-
Verify Android version is 12.0Run 'getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if The displayed version equals 12.0 exactly
-
Confirm MediaTek chipset is in useRun 'getprop ro.hardware' or check /proc/cpuinfo for MediaTek or MTK identifier in the hardware fieldAffected if The output contains MediaTek, MTK, or a MediaTek model number
-
Check if venc video encoder driver is loadedRun 'lsmod | grep -i venc' or check /proc/modules for a venc-related kernel moduleAffected if A venc module is listed as loaded or present in the system
-
Verify venc component is accessibleCheck for /dev/video* nodes or query /sys/class/video4linux/ for video encoder device entriesAffected if Video encoder device nodes exist in /dev or /sys/class/video4linux/
The device is affected if it runs Android 12.0, uses a MediaTek chipset, and has the venc video encoder component available on the system.

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 vendor patches ALPS08810810 and ALPS08805789 via MediaTek firmware updates. Identify all deployed devices using affected MediaTek chipsets and schedule coordinated firmware updates.
