  - nfc: nci: add flush_workqueue to prevent uaf Our detector found a concurrent use-after-free bug when     detaching an NCI device. The main reason for this bug is the unexpected scheduling between the used     delayed mechanism (timer and workqueue). The race can be demonstrated below: Thread-1 Thread-2 |     nci_dev_up() | nci_open_device() | __nci_request(nci_reset_req) | nci_send_cmd | queue_work(cmd_work)     nci_unregister_device() | nci_close_device() | ... del_timer_sync(cmd_timer)[1] | ... | Worker     nci_free_device() | nci_cmd_work() kfree(ndev)[3] | mod_timer(cmd_timer)[2] In short, the cleanup routine     thought that the cmd_timer has already been detached by [1] but the mod_timer can re-attach the timer [2],     even it is already released [3], resulting in UAF. This UAF is easy to trigger, crash trace by POC is like     below [ 66.703713] ================================================================== [ 66.703974] BUG:

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992984 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    nfc: nci: add flush_workqueue to prevent uaf

    Our detector found a concurrent use-after-free bug when detaching an     NCI device. The main reason for this bug is the unexpected scheduling     between the used delayed mechanism (timer and workqueue).

    The race can be demonstrated below:

    Thread-1                           Thread-2                                      | nci_dev_up()                                      |   nci_open_device()                                      |     __nci_request(nci_reset_req)                                      |       nci_send_cmd                                      |         queue_work(cmd_work)     nci_unregister_device()          |       nci_close_device()             | ...
        del_timer_sync(cmd_timer)[1] |     ...                              | Worker     nci_free_device()                | nci_cmd_work()       kfree(ndev)[3]                 |   mod_timer(cmd_timer)[2]

    In short, the cleanup routine thought that the cmd_timer has already     been detached by [1] but the mod_timer can re-attach the timer [2], even     it is already released [3], resulting in UAF.

    This UAF is easy to trigger, crash trace by POC is like below
