CVE-2024-55569
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, and Modem Exynos 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 9110, W920, W930, W1000, Modem 5123, Modem 5300, Modem 5400. The lack of a length check leads to out-of-bounds writes.
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 confidenceMissing input length validation in Samsung Exynos processor and modem firmware allows out-of-bounds memory writes, potentially enabling remote code execution or denial of service. This affects mobile processors, wearable processors, and modem chipsets across numerous Exynos models.

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 your device processor modelOn Android devices, check Settings > About Phone > Processor or use a system info app. On Samsung devices, check Settings > About Phone > Software Information. Look for 'Exynos' and the model number (980, 990, 850, 1080, 2100, 1280, 2200, or 1330).Affected if The device uses any of the listed Exynos processors (980, 990, 850, 1080, 2100, 1280, 2200, or 1330)
-
Confirm firmware version for the baseband/modemGo to Settings > About Phone > Software Information > Baseband version or use *#0011# in the phone dialer (Samsung service menu). Record the full baseband version string.Affected if The baseband version is older than Samsung's latest security patch for your specific Exynos model (you must check Samsung's security bulletins for your model)
-
Check for pending firmware updatesGo to Settings > Software Update > Download and install. Also check if your device manufacturer has released a firmware update that includes the CVE-2024-55569 fix.Affected if A firmware update containing the CVE-2024-55569 fix is available but has not been installed
-
Verify wearable device chipset (if applicable)For Samsung wearables (Galaxy Watch, Galaxy Buds, etc.), check the device settings or product specifications to identify the Exynos chipset model used.Affected if The wearable uses an affected Exynos processor and is running firmware without the security patch
You are affected if your device uses any of the listed Exynos processors (980, 990, 850, 1080, 2100, 1280, 2200, or 1330) and the firmware has not been updated to include Samsung's security patch for CVE-2024-55569.
