Descriptions

In the Linux kernel, the following vulnerability has been resolved:

bounds: Use the right number of bits for power-of-two CONFIG_NR_CPUS

bits_per() rounds up to the next power of two when passed a power of
two. This causes crashes on some machines and configurations.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: límites: utilice el número correcto de bits para potencia de dos CONFIG_NR_CPUS bits_per() redondea a la siguiente potencia de dos cuando se pasa una potencia de dos. Esto provoca fallos en algunas máquinas y configuraciones.

A vulnerability was found in the Linux kernel related to the improper handling of power-of-two values for `CONFIG_NR_CPUS`. The `bits_per()` function incorrectly rounds up to the next power of two when given a power of two, causing crashes on certain systems.
