"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: fsl-asoc-card: set priv->pdev before using it\n\npriv->pdev pointer was set after being used in\nfsl_asoc_card_audmux_init().\nMove this assignment at the start of the probe function, so\nsub-functions can correctly use pdev through priv.\n\nfsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the\ndev struct, used with dev_err macros.\nAs priv is zero-initialised, there would be a NULL pointer dereference.\nNote that if priv->dev is dereferenced before assignment but never used,\nfor example if there is no error to be printed, the driver won't crash\nprobably due to compiler optimisations."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: fsl-asoc-card: establezca priv->pdev antes de usarlo. El puntero priv->pdev se configur\u00f3 despu\u00e9s de usarse en fsl_asoc_card_audmux_init(). Mueva esta asignaci\u00f3n al inicio de la funci\u00f3n de sonda, para que las subfunciones puedan usar correctamente pdev a trav\u00e9s de priv. fsl_asoc_card_audmux_init() elimina la referencia a priv->pdev para obtener acceso a la estructura dev, utilizada con las macros dev_err. Como priv est\u00e1 inicializado en cero, habr\u00eda una desreferencia del puntero NULL. Tenga en cuenta que si se elimina la referencia a priv->dev antes de la asignaci\u00f3n pero nunca se usa, por ejemplo, si no hay ning\u00fan error que imprimir, el controlador nofallar\u00e1 probablemente debido a las optimizaciones del compilador."
