Descriptions
In the Linux kernel, the following vulnerability has been resolved:
powerpc/lib: Validate size for vector operations
Some of the fp/vmx code in sstep.c assume a certain maximum size for the
instructions being emulated. The size of those operations however is
determined separately in analyse_instr().
Add a check to validate the assumption on the maximum size of the
operations, so as to prevent any unintended kernel stack corruption.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: powerpc/lib: validar tamaño para operaciones vectoriales Parte del código fp/vmx en sstep.c asume un cierto tamaño máximo para las instrucciones que se emula. Sin embargo, el tamaño de esas operaciones se determina por separado en analyse_instr(). Agregue una verificación para validar la suposición sobre el tamaño máximo de las operaciones, a fin de evitar daños no deseados en la pila del kernel.
A potential stack corruption flaw was found in arch/powerpc/lib/sstep.c in the Linux kernel. This may lead to compromised Confidentiality or Availability.
