"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Complete cleanup after system-resume errors\n\nA failed system resume can leave the card unusable until reboot.\nusb_audio_resume() jumps to err_out when snd_usb_pcm_resume() or\nsnd_usb_mixer_resume() fails. The error path skips the out: block, which\nrestores D0 and decrements chip->num_suspended_intf.\n\nThe card stays in SNDRV_CTL_POWER_D3hot, so later control access blocks in\nsnd_power_ref_and_wait(). USB core logs an interface resume callback error.\nIt does not retry that callback, so a later callback cannot complete the\nskipped cleanup.\n\nusb_audio_suspend() increments num_suspended_intf before returning success.\nA system-resume callback must consume the system-suspend count even if a\ncomponent resume fails. Otherwise, the stranded count skews later suspend\nand resume cycles.\n\nDo not apply this cleanup to runtime-resume errors. Runtime PM can retry\n-EAGAIN or -EBUSY without another suspend callback. The count must continue\nto describe that suspended interface. Other runtime-resume errors latch\nruntime_error in the PM core and do not cause an immediate callback retry.\n\nBoth parts of the system-resume error path are longstanding. Commit\n88a8516a2128a (\"ALSA: usbaudio: implement USB autosuspend\") introduced\nerr_out past the D0 restore. Commit 862b2509d157c (\"ALSA: usb-audio: Fix\ninconsistent card PM state after resume\") later moved\nnum_suspended_intf-- into the out: block. The error path now skips both\noperations.\n\nNo third-party code is needed to reach the error path.\nsnd_usb_mixer_resume() ends in snd_usb_mixer_activate(), which returns the\nresult of usb_submit_urb() for devices that have a mixer status URB. Its\nmixer->private_resume hook can also fail through scarlett2_init_notify().\nsnd_usb_pcm_resume() issues a SET_CUR request to a UAC3 power domain. It\ncan return -EPIPE or -EIO when the device stalls the request.\n\nRoute a component error through out: only when system_suspend is nonzero.\nContinue to return runtime-resume errors through err_out. Later component\nresume stages remain skipped. The original error still reaches USB core.\nA later transfer can fail if the device did not recover.\n\nI reproduced the system-resume failure on an Audient iD14 MkI with an\nout-of-tree diagnostic mixer resume hook. An injected -EIO on the unpatched\ncore left control readers in uninterruptible sleep in\nsnd_power_ref_and_wait() until a reboot. With this patch, the same failure\nrestored control access. A second system suspend and resume also succeeded\nafter I disabled fault injection."
