CVE-2022-42525
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 fillSetupDataCallInfo_V1_6 of ril_service_1_6.cpp, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-243509750References: N/A
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 confidenceAn out-of-bounds write vulnerability exists in the Android RIL (Radio Interface Layer) service function fillSetupDataCallInfo_V1_6 in ril_service_1_6.cpp, caused by an incorrect bounds check. This allows a local attacker with system-level execution privileges to potentially escalate privileges through 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.
-
Check Android security patch levelRun 'getprop ro.build.version.security_patch' to retrieve the installed security patch dateAffected if The patch level is earlier than November 2022 or the property is empty/unavailable
-
Verify Android OS versionRun 'getprop ro.build.version.release' to get the Android version numberAffected if The device is running any Android version without the November 2022 security update applied
-
Confirm telephony subsystem is activeCheck if the RIL daemon is running using 'ps -A | grep rild' or verify the telephony service is availableAffected if The device has an active telephony/RIL subsystem (this is typically always true on phones)
-
Check for system-level execution contextDetermine if the device allows third-party apps system-level execution or if you have root/adb shell access with system privilegesAffected if The attacker can execute code at the system privilege level on the device
A device is affected if it lacks the November 2022 Android security patch or later and has an active telephony/RIL subsystem reachable from a system-privilege execution context.
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 Android security patches from the November 2022 security bulletin or later, as this is a framework-level vulnerability in the telephony subsystem requiring a system update.
Android devices with December 2022 security patch level or later (Android 12L, Android 13 and later)
- Check your device's current Android security patch level in Settings > About Phone > Android version
- Ensure your device is eligible for manufacturer updates
- Apply the latest available Android system update from your device manufacturer
- Verify the security patch level has been updated beyond the vulnerable period (November 2022 or later)
