A flaw was found in Electron, a framework used for developing cross-platform desktop applications. This vulnerability, known as a use-after-free, affects applications that manage downloads and actively terminate user sessions. It occurs when a user dismisses a file save dialog while the application is simultaneously closing the associated session, causing the application to access memory that has already been released. This can lead to an application crash or, in more severe cases, memory corruption. Apps that do not destroy sessions at runtime, or that do not permit downloads, are not affected.
