In the Linux kernel, the following vulnerability has been resolved:
iommu/omap: Fix buffer overflow in debugfs
There are two issues here:
1) The "len" variable needs to be checked before the very first write. Otherwise if omap2_iommu_dump_ctx() with "bytes" less than 32 it is a buffer overflow. 2) The snprintf() function returns the number of bytes that *would* have been copied if there were enough space. But we want to know the number of bytes which were *actually* copied so use scnprintf() instead.
