CVE-2026-57546

Summary

This vulnerability allows a transient denial-of-service (DOS) condition when processing continuous receive commands with zero-sized global configuration overrides. The flaw occurs in Qualcomm's firmware implementations across multiple device types, causing temporary system unresponsiveness that can disrupt operations.

Exploitability

Exploitation appears difficult without specific preconditions, as the vulnerability requires sending a specially crafted continuous receive command with a zero-sized global configuration override, but no public exploit references are available.

Blast radius

The impact is limited to transient DOS conditions affecting system responsiveness, with potential disruption to network connectivity and device management functions across affected Qualcomm-based devices in the field.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to firmware version 2.590 or later for affected devices, specifically targeting the Qualcomm-based systems including FastConnect 7800, Orne, Pandeiro, and Congo devices.
