  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nrtc: msc313: fix NULL deref in shared IRQ handler at probe\n\nmsc313_rtc_probe() calls devm_request_irq() with IRQF_SHARED and\n\u0026pdev-\u003edev as the cookie, but platform_set_drvdata() is only called\nlater after the clock setup. With a shared IRQ line, another device\non the same line can trigger the handler in that window. The\nhandler does dev_get_drvdata() on the cookie, gets NULL, and\ndereferences priv-\u003ertc_base in interrupt context.\n\nPass priv as the cookie directly so the handler reads it from\ndev_id without the lookup, removing the dependency on probe order.",
