Subject: nfs_fchown_async: fix nullptr dereference
X-Git-Tag: upstream/1.9.6^2~100
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=6b1f14ca0177a25a72eaf1f62ed1ad00f6ae4f5f;p=deb_libnfs.git

nfs_fchown_async: fix nullptr dereference

nfs_chown_data is hooked up under nfs_cb_data->continue_data but
no ->free_continue_data is configured, so once free_nfs_cb_data is
invoked it will trip over a nullptr.
