"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvt: fix memory overlapping when deleting chars in the buffer\n\nA memory overlapping copy occurs when deleting a long line. This memory\noverlapping copy can cause data corruption when scr_memcpyw is optimized\nto memcpy because memcpy does not ensure its behavior if the destination\nbuffer overlaps with the source buffer. The line buffer is not always\nbroken, because the memcpy utilizes the hardware acceleration, whose\nresult is not deterministic.\n\nFix this problem by using replacing the scr_memcpyw with scr_memmovew."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vt: corrige la superposici\u00f3n de memoria al eliminar caracteres en el b\u00fafer. Se produce una copia de memoria superpuesta al eliminar una l\u00ednea larga. Esta copia superpuesta de memoria puede causar corrupci\u00f3n de datos cuando scr_memcpyw est\u00e1 optimizado para memcpy porque memcpy no garantiza su comportamiento si el b\u00fafer de destino se superpone con el b\u00fafer de origen. El b\u00fafer de l\u00ednea no siempre est\u00e1 roto, porque memcpy utiliza la aceleraci\u00f3n de hardware, cuyo resultado no es determinista. Solucione este problema reemplazando scr_memcpyw con scr_memmoew."
