Title

net: atlantic: fix aq_vec index out of range error

Summary

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: fix aq_vec index out of range error The final update statement of the for loop exceeds the array range, the dereference of self->aq_vec[i] is not checked and then leads to the index out of range error. Also fixed this kind of coding style in other for loop.

No adjacency is required since a LANE client is an ordinary routed IP host.\nAC:L - The read-after-free is unconditional on every successful send, with no race and no memory-layout precondition: `adummy_send()` and `atmtcp_v_send()` free the skb synchronously and return 0, after which `lec_send()` always dereferences `skb-\u003elen`. Even against hardware ATM drivers that free asynchronously via `vcc-\u003epop()`, the attacker simply drives traffic to hit it repeatedly.\nPR:N - Triggering requires no credentials on the target \u2014 a remote peer merely causes a frame to be transmitted on the emulated LAN. The `capable(CAP_NET_ADMIN)` checks on `ATMLEC_CTRL`/`ATMLEC_DATA` gate only the administrative LANE setup, not the vulnerable transmit path, which is also open to any unprivileged local process via a plain `sendto()`.\nUI:N - No victim action is needed; the freed-object read happens automatically in the netdevice transmit path and in the `lec_arp_check_expire()` workqueue drain.\nS:U - The stale read and the corrupted statistics counter are entirely within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or sandbox boundary.\nC:L - The stale `skb-\u003elen` from the freed skbuff is accumulated into `dev-\u003estats.tx_bytes`, which any user can read via `/sys/class/net/lec0/statistics/tx_bytes` or `/proc/net/dev`, yielding a repeatable kernel-heap disclosure \u2014 but it is strictly bounded to 4 bytes from one fixed offset of a `SLAB_NO_MERGE` cache, so it is a limited leak rather than an arbitrary read.\nI:L - Nothing is written into the freed object, so there is no memory corruption or write primitive; the only integrity effect is that attacker-influenced garbage is folded into the interface\u0027s `tx_bytes` counter, falsifying kernel-reported accounting data.\nA:H - This is a genuine use-after-free, and on KASAN- or KFENCE-instrumented kernels the access raises a slab-use-after-free report that panics the machine outright under `panic_on_warn`, which is common in production and CI fleets."

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.
