Security readout for executives and security teams
Plain-English summary
CVE-2024-48290 is a denial-of-service issue in Realtek RTL8762E BLE SDK v1.4.0. A nearby attacker with Bluetooth Low Energy range could disrupt availability by sending a crafted termination packet. The public data does not identify downstream device models or a named patch.
Executive priority
Treat as a moderate availability risk. It is not described as data theft or remote internet compromise, but BLE disruption can matter for operational, medical, access-control, or field devices. Prioritize asset identification and vendor confirmation over emergency response.
Technical view
The issue affects the Bluetooth Low Energy implementation in Realtek RTL8762E BLE SDK v1.4.0. The CVSS vector is AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L, indicating adjacent-network reachability, no privileges, no user interaction, and limited availability impact only. It is mapped to CWE-1284.
Likely exposure
Exposure is most likely in embedded or IoT products built with Realtek RTL8762E BLE SDK v1.4.0. The source bundle does not name specific vendors, device models, firmware versions, or CPEs, so confirmation requires supplier, SBOM, or firmware lineage checks.
Exploitation context
No CISA KEV listing or cited source in the bundle indicates active exploitation. Exploitation requires Bluetooth adjacency rather than internet exposure. Public details describe a crafted ll_terminate_ind packet causing DoS, but the bundle does not provide broader exploit evidence.
Researcher notes
The public record is sparse: affected vendor/product fields are n/a, the description names only Realtek RTL8762E BLE SDK v1.4.0, and no remediation is specified in the provided sources. Avoid assuming downstream device impact without firmware provenance evidence.
Mitigation direction
- Check Realtek and device-vendor guidance for fixed SDK or firmware releases.
- Inventory BLE-enabled products that may use Realtek RTL8762E SDK v1.4.0.
- Request component and firmware confirmation from suppliers for affected devices.
- Apply vendor firmware updates when available and validated.
- Disable BLE where it is not operationally required.
- Prioritize devices where availability loss affects safety or operations.
Validation and detection
- Review SBOMs, firmware notes, and supplier attestations for RTL8762E BLE SDK v1.4.0.
- Confirm whether affected devices expose BLE in deployed environments.
- Check vendor advisories for patch status and affected downstream products.
- Monitor for unexplained BLE disconnects or availability degradation.
- Validate fixes only in controlled lab conditions, without offensive reproduction.

Improper Validation of Specified Quantity in Input
Improper Validation of Specified Quantity in Input represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
