smb: client: fix potential UAF in cifs_stats_proc_write()

...

The vulnerability of the `snd_pcm_lib_preallocate_proc_write()` function in the `sound/core/pcm_memory.c` module, which is part of Linux’s kernel-based audio card support mechanism, allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the sndpcmlibpreallocateprocwrite function in the sound/core/pcmmemory.c module, which is part of Linux’s audio card support, relates to the reallocation of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...
