Description

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

unicode: Fix utf8_load() error path

utf8_load() requests the symbol 'utf8_data_table' and then checks if the
requested UTF-8 version is supported. If it's unsupported, it tries to
put the data table using symbol_put(). If an unsupported version is
requested, symbol_put() fails like this:

kernel BUG at kernel/module/main.c:786!
RIP: 0010:__symbol_put+0x93/0xb0
Call Trace:
<TASK>
? __die_body.cold+0x19/0x27
? die+0x2e/0x50

? __symbol_put+0x93/0xb0
? __symbol_put+0x62/0xb0
utf8_load+0xf8/0x150

That happens because symbol_put() expects the unique string that
identify the symbol, instead of a pointer to the loaded symbol. Fix that
by using such string.
