Title
wifi: ath12k: fix out-of-bound access of qmi_invoke_handler()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix out-of-bound access of qmi_invoke_handler()
Currently, there is no terminator entry for ath12k_qmi_msg_handlers hence
facing below KASAN warning,
==================================================================
BUG: KASAN: global-out-of-bounds in qmi_invoke_handler+0xa4/0x148
Read of size 8 at addr ffffffd00a6428d8 by task kworker/u8:2/1273
CPU: 0 PID: 1273 Comm: kworker/u8:2 Not tainted 5.4.213 #0

The address belongs to the variable:

[...]
==================================================================
Add a dummy terminator entry at the end to assist the qmi_invoke_handler()
in traversing up to the terminator entry without accessing an
out-of-boundary index.

{
"lang": "en",
"value": "AV:L - The vulnerable code is reached by sending a datagram to the ath12k QMI handle\u0027s socket over the local AF_QIPCRTR (QRTR) IPC transport, which requires local system access. QMI is a host-to-firmware control channel and is not exposed to over-the-air or network peers.\nAC:L - The attacker fully controls the QMI header\u0027s type and msg_id fields, so simply sending any value not present in the 3-entry handler table deterministically walks past the array end; the destination ephemeral port range is only 0x4000-0x7fff and is trivially scanned. No race, timing, or uncontrollable precondition is involved.\nPR:L - qrtr_create() performs no capability check for AF_QIPCRTR/SOCK_DGRAM, qrtr_sendmsg() autobinds to an ephemeral port and delivers via the global (non-netns-scoped) qrtr_ports XArray, and qmi_handle_message() does no sender validation for non-response messages, so any unprivileged local user can reach it. Only binding below QRTR_MIN_EPH_SOCKET needs CAP_NET_ADMIN, which is not required here.\nUI:N - The attacker triggers the out-of-bounds access entirely on their own by sending a single crafted QMI datagram. No victim action is needed, and the bug also fires spontaneously on any unrecognized firmware indication.\nS:U - The out-of-bounds read, the resulting corruption, and the wild indirect call all occur within the kernel\u0027s own security authority on the same host. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The loop performs an unbounded out-of-bounds read that walks arbitrary module .rodata until it happens to find a slot with a NULL fn field, and the attacker steers which slot is selected via the type/msg_id he controls. Combined with the garbage qmi_elem_info pointer fed to qmi_decode_message(), this yields wild kernel memory reads well beyond a few bounded bytes.\nI:H - An attacker-selected out-of-bounds slot supplies a bogus ei pointer to qmi_decode_message(), whose qmi_decode() writes elem_len * elem_size bytes at c_struct + ei-\u003eoffset \u2014 an out-of-bounds heap write \u2014 and then calls handler-\u003efn(), an indirect call through an unvalidated pointer read from out-of-bounds memory, giving a control-flow hijack primitive.\nA:H - The out-of-bounds walk can run off the end of the module mapping and the subsequent decode/indirect call through garbage pointers reliably oopses the kernel, as demonstrated by the KASAN global-out-of-bounds report in the fix commit. It is triggerable repeatedly from an unprivileged process."

"value": "AV:L - The vulnerable code is reached by sending a datagram to the ath12k QMI handle\u0027s socket over the local AF_QIPCRTR (QRTR) IPC transport, which requires local system access. QMI is a host-to-firmware control channel and is not exposed to over-the-air or network peers.\nAC:L - The attacker fully controls the QMI header\u0027s type and msg_id fields, so simply sending any value not present in the 3-entry handler table deterministically walks past the array end; the destination ephemeral port range is only 0x4000-0x7fff and is trivially scanned. No race, timing, or uncontrollable precondition is involved.\nPR:L - qrtr_create() performs no capability check for AF_QIPCRTR/SOCK_DGRAM, qrtr_sendmsg() autobinds to an ephemeral port and delivers via the global (non-netns-scoped) qrtr_ports XArray, and qmi_handle_message() does no sender validation for non-response messages, so any unprivileged local user can reach it. Only binding below QRTR_MIN_EPH_SOCKET needs CAP_NET_ADMIN, which is not required here.\nUI:N - The attacker triggers the out-of-bounds access entirely on their own by sending a single crafted QMI datagram. No victim action is needed, and the bug also fires spontaneously on any unrecognized firmware indication.\nS:U - The out-of-bounds read, the resulting corruption, and the wild indirect call all occur within the kernel\u0027s own security authority on the same host. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The loop performs an unbounded out-of-bounds read that walks arbitrary module .rodata until it happens to find a slot with a NULL fn field, and the attacker steers which slot is selected via the type/msg_id he controls. Combined with the garbage qmi_elem_info pointer fed to qmi_decode_message(), this yields wild kernel memory reads well beyond a few bounded bytes.\nI:H - An attacker-selected out-of-bounds slot supplies a bogus ei pointer to qmi_decode_message(), whose qmi_decode() writes elem_len * elem_size bytes at c_struct + ei-\u003eoffset \u2014 an out-of-bounds heap write \u2014 and then calls handler-\u003efn(), an indirect call through an unvalidated pointer read from out-of-bounds memory, giving a control-flow hijack primitive.\nA:H - The out-of-bounds walk can run off the end of the module mapping and the subsequent decode/indirect call through garbage pointers reliably oopses the kernel, as demonstrated by the KASAN global-out-of-bounds report in the fix commit. It is triggerable repeatedly from an unprivileged process."

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.
