  "summary": "net: ethernet: arc: emac: quiesce interrupts before requesting IRQ",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: arc: emac: quiesce interrupts before requesting IRQ\n\nNormal RX/TX interrupts are enabled later, in arc_emac_open(), so probe\nshould not see interrupt delivery in the usual case. However, hardware may\nstill present stale or latched interrupt status left by firmware or the\nbootloader.\n\nIf probe later unwinds after devm_request_irq() has installed the handler,\nsuch a stale interrupt can still reach arc_emac_intr() during teardown and\nrace with release of the associated net_device.\n\nAvoid that window by putting the device into a known quiescent state before\nrequesting the IRQ: disable all EMAC interrupt sources and clear any\npending EMAC interrupt status bits. This keeps the change hardware-focused\nand minimal, while preventing spurious IRQ delivery from leftover state.",
