  3. CVE-2024-26911
In the Linux kernel, the following vulnerability has been resolved: drm/buddy: Fix alloc_range() error handling code Few users have observed display corruption when they boot the machine to KDE Plasma or playing games. We have root caused the problem that whenever alloc_range() couldn't find the required memory blocks the function was returning SUCCESS in some of the corner cases. The right approach would be if the total allocated size is less than the required size, the function should return -ENOSPC.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/buddy: corrige el código de manejo de errores alloc_range() Pocos usuarios han observado daños en la pantalla cuando inician la máquina en KDE Plasma o juegan juegos. Hemos causado el problema de que cada vez que alloc_range() no podía encontrar los bloques de memoria requeridos, la función devolvía ÉXITO en algunos de los casos de esquina. El enfoque correcto sería que si el tamaño total asignado es menor que el tamaño requerido, la función debería devolver -ENOSPC.
