Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
unicode: Fix utf8_load() error path<br />
<br />
utf8_load() requests the symbol "utf8_data_table" and then checks if the<br />
requested UTF-8 version is supported. If it&#39;s unsupported, it tries to<br />
put the data table using symbol_put(). If an unsupported version is<br />
requested, symbol_put() fails like this:<br />
<br />
kernel BUG at kernel/module/main.c:786!<br />
RIP: 0010:__symbol_put+0x93/0xb0<br />
Call Trace:<br />

? __symbol_put+0x93/0xb0<br />
? __symbol_put+0x62/0xb0<br />
utf8_load+0xf8/0x150<br />
<br />
That happens because symbol_put() expects the unique string that<br />
identify the symbol, instead of a pointer to the loaded symbol. Fix that<br />
by using such string.
