soc: qcom: mdt_loader: Validate that p_filesz < p_memsz
[ Upstream commit 84168d1b54e76a1bcb5192991adde5176abe02e3 ]
The code validates that segments of p_memsz bytes of a segment will fit
in the provided memory region, but does not validate that p_filesz bytes
will, which means that an incorrectly crafted ELF header might write
beyond the provided memory region.
