Summary

In the Linux kernel, the following vulnerability has been resolved: aoe: fix the potential use-after-free problem in more places For fixing CVE-2023-6270, f98364e92662 ("aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts") makes tx() calling dev_put() instead of doing in aoecmd_cfg_pkts(). It avoids that the tx() runs into use-after-free. Then Nicolai Stange found more places in aoe have potential use-after-free problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe() and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push packet to tx queue. So they should also use dev_hold() to increase the refcnt of skb->dev. On the other hand, moving dev_put() to tx() causes that the refcnt of skb->dev be reduced to a negative value, because corresponding dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(), probe(), and aoecmd_cfg_rsp(). This patch fixed this issue.

Those functions also use aoenet_xmit() to push\npacket to tx queue.

It avoids that the tx() runs\ninto use-after-free.\n\nThen Nicolai Stange found more places in aoe have potential use-after-free\nproblem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe()\nand aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push\npacket to tx queue. So they should also use dev_hold() to increase the\nrefcnt of skb-\u003edev.\n\nOn the other hand, moving dev_put() to tx() causes that the refcnt of\nskb-\u003edev be reduced to a negative value, because corresponding\ndev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(),\nprobe(), and aoecmd_cfg_rsp(). This patch fixed this issue."

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.
