Summary
ksmbd: fix slab-out-of-bounds in smb2_allocate_rsp_buf
Details

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

ksmbd: fix slab-out-of-bounds in smb2allocatersp_buf

If ->ProtocolId is SMB2TRANSFORMPROTONUM, smb2 request size validation could be skipped. if request size is smaller than sizeof(struct smb2queryinforeq), slab-out-of-bounds read can happen in smb2allocaterspbuf(). This patch allocate response buffer after decrypting transform request. smb3decryptreq() will validate transform request size and avoid slab-out-of-bound in smb2allocaterspbuf().
