Title: kernel de Linux
Description:  En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pwm: corrige el error de double shift. Estas enumeraciones se pasan a set/test_bit(). Las funciones set/test_bit() toman un número de bit en lugar de un valor desplazado. Pasar un valor desplazado es un error de doble desplazamiento, como hacer BIT(BIT(1)). El error de doble turno no causa un problema aquí porque solo estamos verificando 0 y 1, pero si el valor era 5 o superior, puede provocar un desbordamiento del búfer.

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

pwm: Fix double shift bug

These enums are passed to set/test_bit().  The set/test_bit() functions
take a bit number instead of a shifted value.  Passing a shifted value
is a double shift bug like doing BIT(BIT(1)).  The double shift bug
doesn't cause a problem here because we are only checking 0 and 1 but
if the value was 5 or above then it can lead to a buffer overflow.

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
