In this\ncase, a crash occurs because runtime suspend/resume dereferences\nqmp->phy pointer, which is not yet initialized:\n        `if (!qmp->phy->init_count) {`\n\nThis can also happen if user re-enables runtime-pm via the sysfs\nattribute before qmp phy is initialized.\n\nSimilarly to other qcom phy drivers, introduce a qmp->phy_initialized\nvariable that can be used to avoid relying on the possibly uninitialized\nphy pointer.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/03455404fb6cbfd65842695df26739853fc1516b","tags":[]},{"url":"https://git.kernel.org/stable/c/142c5593379273264474f31d5956b1a0065cd576","tags":[]},{"url":"https://git.kernel.org/stable/c/5547fd950d6bf72de861b6934341e7bb0888640c","tags":[]},{"url":"https://git.kernel.org/stable/c/9b28287c5dea7650e6dd317591b9e82b6e145365","tags":[]},{"url":"https://git.kernel.org/stable/c/f4e39ab1b2009a89c60e4cb9dbefb8140d405eff","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
