CVE-2024-5660Network attack vector

Host information disclosure via HPA translation bypass

Published Dec 10, 2024 · Updated Dec 16, 2024

Improper resource exposure in affected Arm CPU cores allows guest OS users to disclose host information through HPA translation errors. Hardware Page Aggregation can cause Stage-1 or Stage-2 address translation to bypass Stage-2 or GPT protection rather than preserving the intended isolation boundary. Reachability requires HPA to remain enabled on an affected core in a virtualization environment where a modified or compromised guest operates.
