CVE-2026-20410
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 imgsys, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10362552; Issue ID: MSV-5760.
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 confidenceIn the imgsys graphics processing component, a missing bounds check allows an out-of-bounds write vulnerability. A malicious actor with System privilege can exploit this to escalate privileges locally without 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.
-
Check Android versionRun 'getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if Version is 15.0 exactly
-
Verify imgsys component presenceCheck for imgsys driver or service files in /vendor/lib/ or /system/lib/ directories (e.g., 'ls /vendor/lib/*imgsys*' or check /proc/mtk_resizer for MediaTek imgsys)Affected if imgsys graphics processing component is present on the device
-
Identify processes with System privilegeRun 'ps -A | grep -E "system|root"' to list processes running as system or root userAffected if Attacker already has System-level access, enabling exploitation of this vulnerability
-
Check imgsys driver permissionsInspect /sys/class/misc/imgsys or similar imgsys-related entries in /dev/ for world-writable permissions using 'ls -la /dev/misc/imgsys 2>/dev/null' or equivalent pathAffected if imgsys device node has overly permissive access (world-writable or readable/writable by non-privileged users)
A device is affected if it runs Android 15.0 and contains the imgsys graphics component, especially if untrusted processes can access imgsys functionality or if the device has already been compromised to System privilege level.

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.
dbcve · scopedApply patch ALPS10362552 to implement proper bounds checking in the imgsys component. Since the vulnerability requires System-level access, ensure strict access controls around imgsys functionality.
- Contact your device manufacturer to confirm they have applied MediaTek patch ALPS10362552 for issue MSV-5760
- Verify your device has the latest Android Security Update installed
- If your device manufacturer has not released a patch containing ALPS10362552, request timeline for patch delivery
- For organizations, inventory Android 15.0 devices using MediaTek chipsets and track patch status
