Transient DOS when processing target power rate tables during channel configuration.
AnalysisAI
Transient denial of service in Qualcomm Snapdragon occurs during target power rate table processing when configuring wireless channels, caused by a buffer over-read vulnerability. The vulnerability affects all Snapdragon versions and requires adjacent network access with no authentication or user interaction, resulting in service interruption but no data compromise or unauthorized access.
Technical ContextAI
The vulnerability stems from a CWE-126 buffer over-read condition in the wireless channel configuration subsystem, specifically within the target power rate table parser. This is a classic bounds-checking failure where the code reads beyond allocated memory boundaries during processing of power regulation parameters used in RF (radio frequency) channel setup. The affected component is part of Qualcomm's Snapdragon system-on-chip (SoC) architecture, which handles cellular baseband and wireless protocol processing. The attack surface is the wireless configuration interface, which processes channel parameters including power rate tables transmitted from the network or local wireless management interfaces.
RemediationAI
Obtain and apply the Qualcomm Snapdragon firmware update released in May 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/may-2026-bulletin.html), which addresses the buffer over-read condition in the power rate table parser. Exact patched firmware versions are not yet specified in available data; consult the bulletin for OEM-specific and device-model-specific update packages. As an interim compensating control, disable wireless dynamic channel configuration features if supported by your device or restrict RF parameter updates to authenticated network sources only. Organizations managing Snapdragon-based devices (smartphones, tablets, network appliances, automotive systems) should prioritize firmware update deployment based on device criticality and wireless exposure.
