There is no network, Bluetooth, or USB packet path into this GSC chip.\nAC:L - snd_harmony_create() calls request_irq() before spin_lock_init() and before pcm_init()'s harmony_disable_interrupts(). Firmware leftover DSTATUS_IE plus pending PN/RN lets gsc_asic_unmask_irq() deliver snd_harmony_interrupt() immediately against uninitialized h->lock, without an attacker-uncontrollable race.\nPR:N - snd_harmony_create() performs no capability or authentication checks before request_irq(). On GSC/LASI PA-RISC workstations and servers with Harmony, kernel/udev enumeration runs the vulnerable probe automatically without an OS account or user-namespace privilege.\nUI:N - No victim action is required. A pending Harmony interrupt during driver probe at boot or module autoload invokes the uninitialized-lock IRQ path without anyone opening ALSA PCM or control nodes.\nS:U - Impact is uninitialized spinlock use and DMA next-address programming inside the host kernel Harmony driver. This does not cross a VM, IOMMU, or sandbox security boundary.\nC:H - snd_harmony_interrupt() takes uninitialized h->lock in hard-IRQ context and, with psubs/csubs still NULL, programs HARMONY_PNXTADD from zeroed sdma so the chip DMAs from physical address 0. That undefined lock/DMA behavior can disclose kernel memory rather than a small bounded leak.\nI:H - On SMP PA-RISC (defconfig), probe can spin_lock_init() h->lock while the IRQ handler still holds the zeroed lock, and the handler writes HARMONY_RNXTADD/PNXTADD (including 0) in that window. That lock-state corruption and invalid DMA programming are write/control-flow primitives, not a pure crash.\nA:H - Taking uninitialized h->lock in snd_harmony_interrupt() during probe hits DEBUG_SPINLOCK bad-magic BUG, lockdep non-static-key failure, oops/panic, or a hung IRQ/DMA path on affected PA-RISC machines, fully denying availability."}]}], "affected": [{"product": "Linux",
