Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.0

Description A race condition exists in the amdisp i2c device during the resume-probe process. The issue occurs because the pm runtime get sync() function, called before i2c dw probe(), triggers a power management resume that powers on the ISP and invokes the amdisp i2c runtime resume before the probe completes. This leads to a NULL dereferencing issue.

Recommendations Update the Linux kernel to version 7.0 or later. As a temporary mitigation, restrict the use of the amdisp i2c device until the update is applied.
