"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: qcom-rng - fix infinite loop on requests not multiple of WORD_SZ\n\nThe commit referenced in the Fixes tag removed the 'break' from the else\nbranch in qcom_rng_read(), causing an infinite loop whenever 'max' is\nnot a multiple of WORD_SZ. This can be reproduced e.g. by running:\n\n kcapi-rng -b 67 >/dev/null\n\nThere are many ways to fix this without adding back the 'break', but\nthey all seem more awkward than simply adding it back, so do just that.\n\nTested on a machine with Qualcomm Amberwing processor."

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: crypto: qcom-rng: corrige el bucle infinito en solicitudes que no sean m\u00faltiples de WORD_SZ. El commit a la que se hace referencia en la etiqueta Fixes elimin\u00f3 la 'ruptura' de la rama else en qcom_rng_read(), lo que provoc\u00f3 una bucle infinito siempre que 'max' no sea un m\u00faltiplo de WORD_SZ. Esto se puede reproducir, por ejemplo, ejecutando: kcapi-rng -b 67 >/dev/null Hay muchas formas de solucionar este problema sin volver a agregar el 'descanso', pero todas parecen m\u00e1s inc\u00f3modas que simplemente volver a agregarlo, as\u00ed que hazlo. Probado en una m\u00e1quina con procesador Qualcomm Amberwing."
