Title
i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition
Summary
In the Linux kernel, the following vulnerability has been resolved:
i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition
In the svc_i3c_master_probe function, &master->hj_work is bound with
svc_i3c_master_hj_work, &master->ibi_work is bound with
svc_i3c_master_ibi_work. And svc_i3c_master_ibi_work can start the
hj_work, svc_i3c_master_irq_handler can start the ibi_work.
If we remove the module which will call svc_i3c_master_remove to
make cleanup, it will free master->base through i3c_master_unregister
while the work mentioned above will be used. The sequence of operations
that may lead to a UAF bug is as follows:
CPU0 CPU1
| svc_i3c_master_hj_work
svc_i3c_master_remove |
i3c_master_unregister(&master->base)|
device_unregister(&master->dev) |
device_release |
//free master->base |
| i3c_master_do_daa(&master->base)
| //use master->base
Fix it by ensuring that the work is canceled before proceeding with the
cleanup in svc_i3c_master_remove.

No network or remote protocol data reaches this path.\nAC:L - The attacker drives one side of the race directly (repeatable bind/unbind cycles) while the hot-join work is generated by ordinary I3C bus activity, and the window can be widened and retried indefinitely until it is won; per kernel scoring practice a UAF race whose triggering side is attacker-initiated is Low.\nPR:L - The teardown path is reached from local userspace device-management interfaces on the I3C master device, and no authentication beyond ordinary local access to the device/driver interfaces is required to keep re-triggering the removal path; scored at the lower privilege tier consistent with comparable driver-removal UAFs.\nUI:N - No victim action is needed \u2014 the removal path and the hot-join work both proceed automatically once the unbind is issued and a hot-join IBI arrives.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own memory and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free lets `i3c_master_do_daa()` read `master-\u003ebase`, `master-\u003ebus`, and `master-\u003eops` out of a freed and potentially re-allocated slab object, so an attacker who grooms the heap can read back kernel memory contents through the stale object.\nI:H - The freed object is dereferenced for an indirect call (`master-\u003eops-\u003edo_daa(master)`) and for lock manipulation, so heap spraying over the freed allocation gives a control-flow hijack and arbitrary-write primitive rather than a mere stale read.\nA:H - Even unexploited, the use-after-free corrupts kernel state and dereferences freed pointers, reliably producing an oops or panic and taking down the system."

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.
