  "details": "In the Linux kernel, the following vulnerability has been resolved:  mailbox: mtk-adsp: fix UAF during device teardown  When the SOF audio driver fails to initialize (e.g. firmware boot timeout), its devres unwind frees the snd_sof_dev object that the mailbox client (mtk-adsp-ipc) reaches via chan-\u003ecl-\u003erx_callback. The mtk-adsp-mailbox shutdown clears the mailbox command registers but leaves the IRQ line unmasked, so a late interrupt can still queue a threaded handler after mbox_free_channel() had cleared chan-\u003ecl, and mbox_chan_received_data() would then trigger UAF:    BUG: KASAN: slab-use-after-free in sof_ipc3_validate_fw_version    sof_ipc3_validate_fw_version    sof_ipc3_do_rx_work    sof_ipc3_rx_msg    mt8196_dsp_handle_request    mtk_adsp_ipc_recv    mbox_chan_received_data    mtk_adsp_mbox_isr    irq_thread_fn   Freed by task ...:    kfree    devres_release_all    really_probe    ...

In addition, request the IRQ with IRQF_NO_AUTOEN so it stays masked between probe and the first client bind — otherwise an early interrupt can crash on chan-\u003ecl == NULL in mbox_chan_received_data().",
