Title
atm: atmtcp: Prevent arbitrary write in atmtcp_recv_control().
Summary
In the Linux kernel, the following vulnerability has been resolved:
atm: atmtcp: Prevent arbitrary write in atmtcp_recv_control().
syzbot reported the splat below. [0]
When atmtcp_v_open() or atmtcp_v_close() is called via connect()
or close(), atmtcp_send_control() is called to send an in-kernel
special message.
The message has ATMTCP_HDR_MAGIC in atmtcp_control.hdr.length.
Also, a pointer of struct atm_vcc is set to atmtcp_control.vcc.
The notable thing is struct atmtcp_control is uAPI but has a
space for an in-kernel pointer.
struct atmtcp_control {
struct atmtcp_hdr hdr; /* must be first */
...
atm_kptr_t vcc; /* both directions */
...
} __ATM_API_ALIGN;
typedef struct { unsigned char _[8]; } __ATM_API_ALIGN atm_kptr_t;
The special message is processed in atmtcp_recv_control() called
from atmtcp_c_send().
atmtcp_c_send() is vcc->dev->ops->send() and called from 2 paths:
1. .ndo_start_xmit() (vcc->send() == atm_send_aal0())
2. vcc_sendmsg()
The problem is sendmsg() does not validate the message length and
userspace can abuse atmtcp_recv_control() to overwrite any kptr
by atmtcp_control.
Let's add a new ->pre_send() hook to validate messages from sendmsg().

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
