CVE-2026-31572

A flaw was found in the Linux kernel's i2c: designware: amdisp component. A race condition exists between the device's probe and runtime Power Management (PM) resume operations. When pm_runtime_get_sync() is called before i2c_dw_probe(), it can prematurely trigger the amdisp i2c runtime resume before the device's probe process is complete. This timing issue can lead to a NULL dereferencing error, potentially causing system instability or a denial of service.

Upstream closes an AMD ISP / Designware I2C resume-vs-probe race that could leave the adapter in an inconsistent power state. Red Hat recommends patched kernels for affected embedded/SoC stacks. No generic unload mitigation is documented for this built-in style path.
