Remote service interruption via empty encrypted key
Published Feb 6, 2024 · Updated Aug 21, 2024
NULL pointer dereference in Qualcomm WLAN Firmware allows remote attackers to interrupt service via an empty encrypted key. The key-unwrapping path accepts an empty or NULL encrypted-key input and dereferences the resulting invalid pointer, transiently stopping the service. No authentication or user interaction is required, and the documented consequence is limited to a transient availability interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
