CVE-2023-30438 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. An internally discovered vulnerability in PowerVM on IBM Power9 and Power10 systems could allow an attacker with privileged user access to a logical partition to perform an undetected violation of the isolation between logical partitions which could lead to data leakage or the execution of arbitrary code in other logical partitions on the same physical server. IBM X-Force ID: 252706.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
