Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The enc dec hypercall() function accepted a page count instead of a size, requiring callers to round up values. This resulted in incorrect marking of pages as decrypted during live migration when non-page aligned virtual addresses were used, leading to data corruption. Live migration relies on accurate encryption status to function correctly.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
