      "value": "A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation."

La funci\u00f3n qxl_mode_dumb_create() desreferencia el qobj devuelto por qxl_gem_object_create_with_handle(), pero el identificador es el \u00fanico que contiene una referencia a \u00e9l. Esta falla permite a un atacante adivinar el valor de identificador devuelto y desencadenar un problema de use-after-free, lo que podr\u00eda provocar una denegaci\u00f3n de servicio o una escalada de privilegios."
