"value": "A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability."

"value": "Se encontr\u00f3 un desbordamiento de b\u00fafer en la regi\u00f3n heap de la memoria en el subsistema LightNVM del kernel de Linux. El problema es debido a la falta de comprobaci\u00f3n apropiada de la longitud de los datos suministrados por el usuario antes de copiarlos en un b\u00fafer de longitud fija en la regi\u00f3n heap de la memoria. Esta vulnerabilidad permite a un atacante local escalar privilegios y ejecutar c\u00f3digo arbitrario en el contexto del kernel. El atacante debe obtener primero la capacidad de ejecutar c\u00f3digo con altos privilegios en el sistema objetivo para explotar esta vulnerabilidad."
