CVE-2022-26468
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 preloader (usb), there is a possible out of bounds write due to a missing bounds check. 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 needed for exploitation. Patch ID: ALPS07168125; Issue ID: ALPS07168125.
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 confidenceA missing bounds check in the USB preloader component allows an out-of-bounds write, potentially enabling local privilege escalation for an attacker with physical device access. The vulnerability requires user interaction to exploit and affects the early boot chain.

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' in ADB shell or check Settings > About Phone > Android versionAffected if The version is exactly 11.0 or 12.0 (these are the only affected versions)
-
Verify USB preloader is accessibleCheck if the device allows USB preloader mode or firmware download mode (often called Download Mode, EDL mode, or factory cable mode). Attempt to enter this mode per device-specific instructions.Affected if USB preloader/firmware download mode is reachable and the boot chain is not locked down
-
Check boot loader lock statusRun 'fastboot oem device-info' or check if the bootloader shows as 'locked' when attempting fastboot commandsAffected if Bootloader is unlocked or allows unsigned firmware flashing
-
Confirm patch deploymentContact the device vendor or check the build fingerprint for ALPS07168125 patch identifier in the bootloader/firmware version string. On some devices, check 'getprop ro.build.version.security_patch' for the monthly patch level.Affected if The ALPS07168125 patch is not present in the firmware/bootloader build
Affected if running Android 11.0 or 12.0 specifically AND USB preloader mode is accessible AND the ALPS07168125 patch has not been applied to the bootloader firmware.

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 patch ALPS07168125 to the firmware/bootloader. Since physical access is required, ensure devices are secured against unauthorized physical access and verify the patch is deployed in production builds.
