CVE-2023-41111
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 issue was discovered in Samsung Mobile Processor, Wearable Processor, Automotive Processor, and Modem (Exynos 9810, 9610, 9820, 980, 850, 1080, 2100, 2200, 1280, 1380, 1330, 9110, W920, Modem 5123, Modem 5300, and Auto T5123). Improper handling of a length parameter inconsistency can cause abnormal termination of a mobile phone. This occurs in the RLC task and RLC module.
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 denial of service vulnerability in the RLC (Radio Link Control) task and module of Samsung Exynos processors and modems. The issue stems from improper validation of a length parameter, which when inconsistent causes abnormal termination (crash/reset) of the mobile device. This affects multiple generations of mobile, wearable, automotive processors and modems.

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 Exynos processor variant in the deviceCheck the device specifications or system information to confirm the exact Exynos model number (e.g., Exynos 9810, 9820, 2100, etc.)Affected if The device uses any of the listed affected Exynos chips: 9810, 9610, 9820, 980, 850, 1080, 2100, or 2200
-
Check the Android security patch levelOn the device, go to Settings > About Phone > Software Information > Security patch level. Record the date shown.Affected if The security patch level is earlier than the date Samsung released the fix for CVE-2023-41111 (consult Samsung's security bulletin for the specific patch date)
-
Verify the modem/baseband firmware versionAccess the device's modem firmware information via engineering mode or diagnostic tools (typically *#*#197328640#*#* or similar on Samsung devices), or check via AT commandsAffected if The modem firmware version has not been updated to include the CVE-2023-41111 fix from Samsung
-
Confirm vendor update availabilityCheck for pending system or firmware updates in Settings > Software Update on the device, or consult the device manufacturer's support pages for the specific modelAffected if Updates are available but have not been installed, or the device is no longer receiving security updates from the vendor
A device is affected if it contains any of the listed Exynos processors (9810, 9610, 9820, 980, 850, 1080, 2100, 2200) and has not received the Samsung security firmware update addressing CVE-2023-41111.

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-supplied firmware/security updates from Samsung for affected processors. No user-facing workarounds available; this is a firmware-level issue requiring patch deployment through device vendor update channels.
