Descriptions
In the Linux kernel, the following vulnerability has been resolved:
NFS: fix an incorrect limit in filelayout_decode_layout()
The "sizeof(struct nfs_fh)" is two bytes too large and could lead to
memory corruption. It should be NFS_MAXFHSIZE because that's the size
of the ->data[] buffer.
I reversed the size of the arguments to put the variable on the left.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: NFS: corrige un límite incorrecto en filelayout_decode_layout() El "sizeof(struct nfs_fh)" es dos bytes demasiado grande y podría provocar daños en la memoria. Debería ser NFS_MAXFHSIZE porque ese es el tamaño del búfer ->datos[]. Invertí el tamaño de los argumentos para poner la variable a la izquierda.
