n the Linux kernel, the following vulnerability has been resolved: openrisc: traps: Don't send signals to kernel mode threads OpenRISC exception handling sends signals to user processes on floating point exceptions and trap instructions (for debugging) among others. There is a bug where the trap handling logic may send signals to kernel threads, we should not send these signals to kernel threads, if that happens we treat it as an error. This patch adds conditions to die if the kernel receives these exceptions in kernel mode code.

Summary
  • (es) En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: openrisc: trampas: no envía señales a subprocesos en modo kernel. El manejo de excepciones de OpenRISC envía señales a los procesos del usuario sobre excepciones de punto flotante e instrucciones de captura (para depuración), entre otros. Hay un error en el que la lógica de manejo de trampas puede enviar señales a los subprocesos del kernel. No debemos enviar estas señales a los subprocesos del kernel; si eso sucede, lo tratamos como un error. Este parche agrega condiciones para morir si el kernel recibe estas excepciones en el código del modo kernel.
