Title
USB: serial: io_edgeport: fix use after free in debug printk
Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: serial: io_edgeport: fix use after free in debug printk
The "dev_dbg(&urb->dev->dev, ..." which happens after usb_free_urb(urb)
is a use after free of the "urb" pointer. Store the "dev" pointer at the
start of the function to avoid this issue.

"value": "AV:L - The command URBs whose completion handler contains the defect are generated by ordinary tty operations (open/close, tcsetattr, TIOCMSET/TIOCMBIS, TIOCSBRK) on /dev/ttyUSB*, so a local user on a machine with an Edgeport device attached drives the vulnerable path via syscalls. This matches the kernel.org CNA\u0027s consistent treatment of USB-serial host driver flaws as local.\nAC:L - No race has to be won and no memory layout has to be groomed \u2014 the attacker simply issues command-generating ioctls and the released urb is dereferenced whenever the transfer completes with a nonzero status (stall, protocol error, shutdown, unlink), which is repeatable at will.\nPR:L - Only access to the /dev/ttyUSB* node is required; there is no capability check anywhere between the tty entry points and write_cmd_usb(), and on embedded, automotive and Android-style deployments the serial node is routinely readable/writable by unprivileged service or app users.\nUI:N - The attacker performs all the steps itself by opening and configuring the serial port; no separate victim has to open a file, mount anything, or take any action.\nS:U - The released urb and any consequent corruption stay within the kernel\u0027s own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a use-after-free read: the stale urb\u0027s -\u003edev field is loaded and dereferenced, so if the slab object is reallocated with attacker-influenced content the pointer chase can be steered to read arbitrary kernel memory, which is then formatted into the kernel log.\nI:H - Per use-after-free scoring, control over the reallocated urb contents makes the dereferenced device pointer attacker-influenced, and the resulting struct device accesses can be leveraged toward corrupting kernel state and hijacking control flow.\nA:H - Dereferencing a released urb and the device pointer read out of it readily faults or trips KASAN/slab debugging, producing an oops or panic that takes down the kernel."

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.
