      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmailbox: mtk-adsp: fix UAF during device teardown\n\nWhen the SOF audio driver fails to initialize (e.g. firmware boot\ntimeout), its devres unwind frees the snd_sof_dev object that the\nmailbox client (mtk-adsp-ipc) reaches via chan->cl->rx_callback.\nThe mtk-adsp-mailbox shutdown clears the mailbox command registers\nbut leaves the IRQ line unmasked, so a late interrupt can still\nqueue a threaded handler after mbox_free_channel() had cleared\nchan->cl, and mbox_chan_received_data() would then trigger UAF:\n\n  BUG: KASAN: slab-use-after-free in sof_ipc3_validate_fw_version\n   sof_ipc3_validate_fw_version\n   sof_ipc3_do_rx_work\n   sof_ipc3_rx_msg\n   mt8196_dsp_handle_request\n   mtk_adsp_ipc_recv\n   mbox_chan_received_data\n   mtk_adsp_mbox_isr\n   irq_thread_fn\n  Freed by task ...:\n   kfree\n   devres_release_all\n   really_probe\n   ... (sof-audio-of-mt8196 probe failure)\n\nThe crash was observed roughly three seconds after the failed probe.\n\ndisable_irq() in shutdown and enable_irq() in startup. disable_irq()\nalso waits for any in-flight interrupts, so by the time\nmbox_free_channel() proceeds to clear chan->cl no rx_callback can run.\n\nIn addition, request the IRQ with IRQF_NO_AUTOEN so it stays masked\nbetween probe and the first client bind — otherwise an early interrupt\ncan crash on chan->cl == NULL in mbox_chan_received_data().",
