CVE-2022-22271
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 · uneditedA missing input validation before memory copy in TIMA trustlet prior to SMR Jan-2022 Release 1 allows attackers to copy data from arbitrary memory.
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 arbitrary memory read vulnerability in Samsung's TIMA (TrustZone-based Integrity Measurement Architecture) trustlet caused by missing input validation before a memory copy operation. Attackers can exploit this to read data from arbitrary memory locations, potentially exposing sensitive information from the trusted execution environment.

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 the device is a Samsung model with TIMA supportIdentify the device manufacturer and model. TIMA (TrustZone-based Integrity Measurement Architecture) is a Samsung-specific security feature implemented in the TrustZone trusted execution environment. Only Samsung devices that implement TIMA are potentially affected.Affected if The device is not a Samsung product or does not implement TIMA trustlet
-
Check the Android OS versionNavigate to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The Android version is 9.0, 10.0, or 11.0 (exact matches as listed in affected versions)
-
Verify TIMA trustlet is present and enabledCheck for the presence of TIMA-related system properties or trustlet files. On affected Samsung devices, TIMA is typically implemented as a trustlet loaded into TrustZone. Examine system properties with 'getprop | grep tima' or check for /vendor/etc/tima or similar TIMA configuration paths if they exist on the device.Affected if TIMAs trustlet is loaded and active on the device
A user is affected if they are running Android 9.0, 10.0, or 11.0 on a Samsung device that implements and enables the TIMA trustlet, as the arbitrary memory read requires the vulnerable TIMA component to be present.

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 the Samsung SMR (Security Maintenance Release) January 2022 Release 1 or later, which contains the fix for the missing input validation in the TIMA trustlet.
SMR Jan-2022 Release 1 or later
- Verify your Samsung device model is eligible for the SMR Jan-2022 security update by checking Samsung's security bulletin at security.samsungmobile.com
- Navigate to Settings > Software update > Download and install on your device to apply the January 2022 Samsung Security Maintenance Release (SMR)
- Confirm the patch was applied by checking Settings > About phone > Software information and verifying the Security patch level shows January 2022 or later
