Description

In the Linux kernel, the following vulnerability has been resolved:

f2fs: compress: fix to avoid use-after-free on dic

Call trace:
__memcpy+0x128/0x250
f2fs_read_multi_pages+0x940/0xf7c

In f2fs_read_multi_pages(), once f2fs_decompress_cluster() was called if
we hit cached page in compress_inode's cache, dic may be released, it needs
break the loop rather than continuing it, in order to avoid accessing
invalid dic pointer.
