In the Linux kernel, the following vulnerability has been resolved: fbdev: smscufx: properly copy ioctl memory to kernelspace The UFX_IOCTL_REPORT_DAMAGE ioctl does not properly copy data from userspace to kernelspace, and instead directly references the memory, which can cause problems if invalid data is passed from userspace. Fix this all up by correctly copying the memory before accessing it within the kernel.
En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: fbdev: smscufx: copiar correctamente la memoria ioctl al espacio del kernel El ioctl UFX_IOCTL_REPORT_DAMAGE no copia correctamente los datos desde el espacio de usuario al espacio del kernel, y en su lugar referencia directamente la memoria, lo que puede causar problemas si se pasan datos inválidos desde el espacio de usuario. Soluciona todo esto copiando correctamente la memoria antes de acceder a ella dentro del kernel.
