Descriptions

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

crypto: s390/aes - Fix buffer overread in CTR mode

When processing the last block, the s390 ctr code will always read
a whole block, even if there isn't a whole block of data left. Fix
this by using the actual length left and copy it into a buffer first
for processing.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: s390/aes - Corrige la sobrelectura del buffer en modo CTR Al procesar el último bloque, el código ctr s390 siempre leerá un bloque completo, incluso si no hay un bloque completo de datos restantes. Solucione este problema utilizando la longitud real restante y cópielo primero en un búfer para procesarlo.
