Descriptions
A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.
Se encontró una falla en el subsistema Netfilter en el kernel de Linux. El problema está en la función nft_byteorder_eval(), donde el código itera a través de un bucle y escribe en la matriz `dst`. En cada iteración, se escriben 8 bytes, pero `dst` es una matriz de u32, por lo que cada elemento solo tiene espacio para 4 bytes. Eso significa que cada iteración sobrescribe parte del elemento anterior, lo que posiblemente lleve a una escritura fuera de los límites. Esta falla permite que un usuario local provoque una denegación de servicio o potencialmente aumente sus privilegios en el sistema.
