CVE-2026-64587

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: ethernet: arc: emac: quiesce interrupts before requesting IRQ<br /> <br /> Normal RX/TX interrupts are enabled later, in arc_emac_open(), so probe<br /> should not see interrupt delivery in the usual case. However, hardware may<br /> still present stale or latched interrupt status left by firmware or the<br /> bootloader.<br /> <br /> If probe later unwinds after devm_request_irq() has installed the handler,<br /> such a stale interrupt can still reach arc_emac_intr() during teardown and<br /> race with release of the associated net_device.<br /> <br /> Avoid that window by putting the device into a known quiescent state before<br /> requesting the IRQ: disable all EMAC interrupt sources and clear any<br /> pending EMAC interrupt status bits. This keeps the change hardware-focused<br /> and minimal, while preventing spurious IRQ delivery from leftover state.
