Name of the Vulnerable Software and Affected Versions Arm (affected versions not specified)

Description The issue arises from the arithmetics in the cache cleaning and invalidation helpers provided by Arm, which can overflow and result in skipping the cache cleaning/invalidation. This means there is no guarantee when all writes will reach the memory, particularly when allocating guest memory and ensuring writes have reached memory before handing over the page to a guest.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
