Subject: x86/boot-image: Don't leak phdrs in arch/x86/boot/compressed/misc.c::Parse_elf()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5067cf53cac9b36d42ebb3a45bb12259d0bc1e68;p=openwrt%2Fstaging%2Fblogic.git

x86/boot-image: Don't leak phdrs in arch/x86/boot/compressed/misc.c::Parse_elf()

We allocate memory with malloc(), but neglect to free it before
the variable 'phdrs' goes out of scope --> leak.
