      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\narm64/sme: Always exit sme_alloc() early with existing storage\n\nWhen sme_alloc() is called with existing storage and we are not flushing we\nwill always allocate new storage, both leaking the existing storage and\ncorrupting the state. Fix this by separating the checks for flushing and\nfor existing storage as we do for SVE.\n\nCallers that reallocate (eg, due to changing the vector length) should\ncall sme_free() themselves."

Cuando se llama a sme_alloc() con el almacenamiento existente y no estamos vaciando, siempre asignaremos nuevo almacenamiento, y ambos filtrar\u00e1n el almacenamiento existente, almacenamiento y corrupci\u00f3n del estado. Solucione este problema separando los controles de descarga y de almacenamiento existente como lo hacemos con SVE. Las personas que llaman que se reasignan (por ejemplo, debido al cambio de la longitud del vector) deben llamar ellos mismos a sme_free()."
