Affected: Linux

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 ? do_trap+0xca/0x110 ? do_error_trap+0x65/0x80 ? __symbol_put+0x93/0xb0 ? exc_invalid_op+0x51/0x70 ? __symbol_put+0x93/0xb0 ? asm_exc_invalid_op+0x1a/0x20 ? __pfx_cmp_name+0x10/0x10 ? __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.
