CVE-2022-32599
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 rpmb, there is a possible out of bounds write due to a logic error. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07460390; Issue ID: ALPS07460390.
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 logic error in the RPMB (Replay Protected Memory Block) driver causes an out-of-bounds write vulnerability. RPMB is a secure storage partition in eMMC/UFS devices used for sensitive data. The flaw allows a local attacker with System execution privileges to potentially escalate privileges via memory corruption.

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.
-
Identify the Android versionCheck the device settings under Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The installed version matches Android 10.0, 11.0, 12.0, or 13.0 exactly (the affected versions listed)
-
Confirm RPMB driver is presentCheck for the RPMB kernel module or device node. On Android, inspect /sys/class/misc/rpmb or look for 'rpmb' in /proc/devices. Alternatively, check kernel config for CONFIG_MMC_RPMB or search for 'rpmb' in /proc/kallsyms via ADB with rootAffected if The RPMB driver/module is loaded or compiled into the kernel (the vulnerability exists in this driver regardless of whether it is actively being used)
-
Verify execution privilegesRun 'id' or 'whoami' in ADB shell to determine current user context. The vulnerability requires System-level privileges to exploitAffected if The attacker has System user or root access on the device - note that this is a privilege escalation flaw, so the attacker would already need elevated (System) privileges to trigger the out-of-bounds write
A device is affected if it runs Android 10.0, 11.0, 12.0, or 13.0 AND has the RPMB driver present, since the logic error in the driver can then be triggered by an attacker with System-level execution privileges.

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 vendor patch ALPS07460390 to address the logic error in the rpmb driver. This is a kernel-level fix requiring system firmware/software update.
