Descriptions
In the Linux kernel, the following vulnerability has been resolved:
vt: fix unicode buffer corruption when deleting characters
This is the same issue that was fixed for the VGA text buffer in commit
39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the
buffer"). The cure is also the same i.e. replace memcpy() with memmove()
due to the overlaping buffers.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: vt: corregida la corrupción del búfer Unicode al eliminar caracteres. Este es el mismo problema que se solucionó para el búfer de texto VGA en la confirmación 39cdb68c64d8 ("vt: corrige la superposición de memoria al eliminar caracteres en el búfer "). La solución también es la misma, es decir, reemplazar memcpy() con memmove() debido a la superposición de buffers.
