CVE-2026-64278

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> i2c: imx-lpi2c: mark I2C adapter when hardware is powered down<br /> <br /> On some i.MX platforms, certain I2C client drivers keep a periodic<br /> workqueue which continues to trigger I2C transfers.<br /> <br /> During system suspend/resume, there exists a time window between:<br /> - suspend_noirq and the system entering suspend<br /> - the system starting to resume and resume_noirq<br /> <br /> In this window, the I2C controller resources such as clock and pinctrl<br /> may already be disabled or not yet restored.<br /> <br /> If a workqueue triggers an I2C transfer in this period, the driver<br /> attempts to access I2C registers while the hardware resources are<br /> unavailable, which may lead to system hang.<br /> <br /> Mark the I2C adapter as suspended during noirq suspend and block new<br /> transfers until resume, ensuring that I2C transfers are only issued<br /> when hardware resources are available.
