CVE-2022-32618
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 typec, there is a possible out of bounds write due to an incorrect calculation of buffer size. This could lead to local escalation of privilege, for an attacker who has physical access to the device, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07262454; Issue ID: ALPS07262454.
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 confidenceA buffer size miscalculation in the USB Type-C (typec) kernel driver causes an out-of-bounds write vulnerability. An attacker with physical access to the device can exploit this to escalate privileges locally without additional execution privileges or 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 versionNavigate to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version is 11.0, 12.0, or 13.0 exactly (exact version matches only)
-
Verify typec kernel driver presenceCheck for the typec driver in /sys/module/ or via 'lsmod | grep typec' command in ADB shellAffected if The typec kernel module is loaded and present on the device
-
Confirm USB Type-C hardware supportCheck if the device has a USB Type-C port via hardware documentation or by inspecting /sys/bus/usb/ or /sys/class/typec/ via ADB shellAffected if USB Type-C hardware is present and exposed for use
A device is affected only if it runs Android 11.0, 12.0, or 13.0 (exact versions) AND has the typec kernel driver loaded AND has USB Type-C hardware support available for exploitation via physical access.
Generated from the published advisory. Verify against your own configuration.
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 vendor patch ALPS07262454 to correct the buffer size calculation in the typec driver. Since physical access is required, ensure devices are protected against unauthorized physical access.
Android Security Patch Level containing ALPS07262454 fix (typically included in Android security bulletins from late 2022 or early 2023)
- 1. Identify the device model and confirm it uses a MediaTek chipset affected by this vulnerability
- 2. Check for and apply the latest Android security patch update from your device manufacturer
- 3. Verify the Android Security Patch Level (SPL) includes the fix for ALPS07262454
- 4. Alternatively, obtain and flash the MediaTek firmware update containing patch ALPS07262454 if provided by the device OEM
- 5. After update, verify the Type-C driver no longer has the buffer size calculation vulnerability
