Subject: util/grub-mkrescue: Fix memory leak in write_part()
X-Git-Tag: grub-2.12-rc1~533
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=eff17a6b2d563fe9a0917e048776ed9ce2da4b80;p=thirdparty%2Fgrub.git

util/grub-mkrescue: Fix memory leak in write_part()

In the function write_part(), the value of inname is not used beyond
the grub_util_fopen() call, so it should be freed to avoid leakage.

Fixes: CID 314028
