Abstract: Systems and methods for generating dynamic quick actions for an application in a web browser. The dynamic quick actions correspond to various functions of an application accessible via a web browser sidebar interface. When a hover event is detected in association with an icon of the application, a quick-actions card is generated that includes quick actions of the application from which the user can select. For instance, a selection of a quick action triggers the web browser to execute an action that causes the application function to be performed. Thus, application functions are able to be surfaced and controlled via a single input device selection (e.g., a mouse click).

Abstract: A method for utilizing computing resources in a vRAN is described. A predicted resource load is determined for data traffic processing of wireless communication channels served by the vRAN using a trained neural network model. The data traffic processing comprises at least one of PHY data processing or MAC processing for a 5G RAN.

Abstract: An exploit detector hooks functions of a WebAssembly engine API that include functions invoked when creating a WebAssembly instance, when permissibly modifying read-write-execute (RWX) memory allocated for a WebAssembly instance, and when calling an exported WebAssembly function. Upon invocation of the hooked instance creation function(s), the detector obtains an address of RWX memory allocated for the instance, reads data stored there, and records an association between the address and the data. If the hooked function(s) for permissibly modifying RWX memory is invoked, the detector updates the data stored in the recorded association with the modified data read from the RWX memory. Based on invocation of the hooked function(s) associated with WebAssembly export function calls, the detector reads the current data in the RWX memory to be executed and compares this data to the data recorded in association with the address. If the actual and expected data differ, the detector detects a browser exploit.
