Descriptions
Use-after-free vulnerability in fs/crypto/ in the Linux kernel before 4.10.7 allows local users to cause a denial of service (NULL pointer dereference) or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be freed prematurely.
Vulnerabilidad de uso después de liberación de memoria en fs/crypto/ en el kernel de Linux en versiones anteriores a 4.10.7 permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL) o posiblemente obtener privilegios revocando el llavero de claves utilizado para cifrado ext4, f2fs o ubifs, provocando que los objetos de transformación criptográfica sean liberados prematuramente.
