CVE-2023-30696
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 · uneditedAn improper input validation in IpcTxGetVerifyAkey in libsec-ril prior to SMR Aug-2023 Release 1 allows attacker to cause out-of-bounds write.
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 confidenceAn improper input validation vulnerability in the IpcTxGetVerifyAkey function in Samsung's libsec-ril library allows attackers to cause an out-of-bounds write, potentially leading to code execution or denial of service. The vulnerability exists in Samsung mobile devices running versions prior to SMR Aug-2023 Release 1.

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 versionOpen Settings > About Phone > Android version, or run `adb shell getprop ro.build.version.release`Affected if The device runs Android 11.0, 12.0, or 13.0
-
Check Samsung Security Patch Level (SMR)Open Settings > About Phone > Software Information > Security patch level, or run `adb shell getprop ro.build.version.security_patch`Affected if The security patch level is earlier than August 2023 (the SMR Aug-2023 Release 1 contains the fix)
-
Verify libsec-ril library presenceRun `adb shell ls -la /vendor/lib/libsec-ril.so` or check via `adb shell getprop | grep sec.ril`Affected if The libsec-ril library exists on the device (this is a Samsung-specific library required for the vulnerability to apply)
A device is affected if it runs Android 11.0, 12.0, or 13.0 with a security patch level before August 2023 and contains the Samsung libsec-ril library.
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 Samsung's SMR Aug-2023 Release 1 or later security patch, which contains the proper input validation fix for the libsec-ril library. Organizations should identify and update affected Samsung devices in their fleet.
SMR Aug-2023 Release 1
- Check the current security patch level on the device under Settings > Security > Security patch level
- Apply the August 2023 Samsung Security Maintenance Release (SMR) update to the device
- Verify the update was successfully applied by confirming the security patch level shows August 2023 or later under Settings > Security > Security patch level
