From this webpage screenshot, the following key information about the vulnerability can be extracted: Vulnerability Description: On certain SDM845/850 devices, a page table walker cache coherency issue causes lockups and resets. This works fine on devices like the Dragonboard 845c, but performs poorly on devices such as the Lenovo Yoga C630. Root Cause: Appears to be an accidental bug introduced during firmware development, possibly due to a change somewhere in the large virtual machine monitor stack to accommodate this, but only introduced after the initial software release (which typically serves as the product baseline). Mitigation: The fix involves rolling back the change to avoid additional speculation due to crashes. Related Commit: This change rolls back commit . Reporter: Dmitry Baryshkov ().
