Descriptions

Use after free in Browser Creation in Google Chrome prior to 104.0.5112.101 allowed a remote attacker who had convinced a user to engage in a specific UI interaction to potentially exploit heap corruption via a crafted HTML page.

Un uso de memoria previamente liberada en Browser Creation en Google Chrome versiones anteriores a 104.0.5112.101, permitía que un atacante remoto que hubiera convencido a un usuario de participar en una interacción específica de la interfaz de usuario pudiera explotar una corrupción de pila por medio de una página HTML diseñada.

A use-after-free issue exists in Chrome 104 and earlier versions. Processing maliciously crafted web content may lead to arbitrary code execution in the browser process. LinkToTextMenuObserver holds a raw pointer to a RenderFrameHost object, but is not owned by the frame host and does not watch for frame host destruction events. Therefore, if an attacker manages to destroy the frame host right after the observer is created but before the timeout task posted in StartLinkGenerationRequestWithTimeout() is executed, use-after-free will occur.
