CVE-2024-35950 HIGH

Published: 2024-05-20 | Last Modified: 2026-08-04 | Status: Modified

Description

In the Linux kernel, the following vulnerability has been resolved: drm/client: Fully protect modes[] with dev->mode_config.mutex The modes[] array contains pointers to modes on the connectors' mode lists, which are protected by dev->mode_config.mutex. Thus we need to extend modes[] the same protection or by the time we use it the elements may already be pointing to freed/reused memory.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/client: Protege completamente los modos[] con dev->mode_config.mutex. La matriz modes[] contiene punteros a los modos en las listas de modos de los conectores, que están protegidos por dev- >mode_config.mutex. Por lo tanto, necesitamos extender modes[] la misma protección o, cuando la usemos, es posible que los elementos ya estén apuntando a la memoria liberada/reutilizada.
