"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: designware: amdisp: Fix resume-probe race condition issue\n\nIdentified resume-probe race condition in kernel v7.0 with the commit\n38fa29b01a6a (\"i2c: designware: Combine the init functions\"),but this\nissue existed from the beginning though not detected.\n\nThe amdisp i2c device requires ISP to be in power-on state for probe\nto succeed. To meet this requirement, this device is added to genpd\nto control ISP power using runtime PM. The pm_runtime_get_sync() called\nbefore i2c_dw_probe() triggers PM resume, which powers on ISP and also\ninvokes the amdisp i2c runtime resume before the probe completes resulting\nin this race condition and a NULL dereferencing issue in v7.0\n\nFix this race condition by using the genpd APIs directly during probe:\n - Call dev_pm_genpd_resume() to Power ON ISP before probe\n - Call dev_pm_genpd_suspend() to Power OFF ISP after probe\n - Set the device to suspended state with pm_runtime_set_suspended()\n - Enable runtime PM only after the device is fully initialized"
