In the Linux kernel, the following vulnerability has been resolved:
mtd: physmap: physmap-bt1-rom: Fix unintentional stack access
Cast &data to (char *) in order to avoid unintentionally accessing the stack.
Notice that data is of type u32, so any increment to &data will be in the order of 4-byte chunks, and this piece of code is actually intended to be a byte offset.
