"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nriscv/purgatory: align riscv_kernel_entry\n\nWhen alignment handling is delegated to the kernel, everything must be\nword-aligned in purgatory, since the trap handler is then set to the\nkexec one. Without the alignment, hitting the exception would\nultimately crash. On other occasions, the kernel's handler would take\ncare of exceptions.\nThis has been tested on a JH7110 SoC with oreboot and its SBI delegating\nunaligned access exceptions and the kernel configured to handle them."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: riscv/purgatory: align riscv_kernel_entry Cuando el manejo de la alineaci\u00f3n se delega al kernel, todo debe estar alineado por palabras en el purgatorio, ya que el controlador de trampas se establece en kexec. Sin la alineaci\u00f3n, alcanzar la excepci\u00f3n finalmente fallar\u00eda. En otras ocasiones, el controlador del kernel se encargar\u00eda de las excepciones. Esto se prob\u00f3 en un SoC JH7110 con oreboot y su SBI que delegaba excepciones de acceso no alineadas y el kernel configurado para manejarlas."
