CVE-2026-17097 [MEDIUM] CWE-129 CVE-2026-17097: IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW95 IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the PowerVM hypervisor call interface. An attacker with root access to a guest partition can issue a specially crafted hypervisor call causing a virtual processor to become permanently unresponsi

CVE-2026-4936 [MEDIUM] CWE-331 CVE-2026-4936: IBM PowerVM Hypervisor Platform KeyStore (PKS) and virtual TPM FW1110.00 through FW1110.20, FW1060.0 IBM PowerVM Hypervisor Platform KeyStore (PKS) and virtual TPM FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 through FW950.H2 use persistent storage key seeds that result in an AES key with reduced strength. An attacker with access to the service processor or HMC could exploit this weakness to derive the encryption key and acc

CVE-2026-17413 [MEDIUM] CWE-129 CVE-2026-17413: IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through F IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the RTAS firmware-to-OS interface. An attacker with administrator-level (root) access to a logical partition can send a specially crafted request to partition firmware, causing

CVE-2026-4937 [MEDIUM] CWE-331 CVE-2026-4937: IBM PowerVM Hypervisor FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 throug IBM PowerVM Hypervisor FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 through FW950.H2 could allow a local attacker with administrative privileges to decrypt encrypted data due to certain hypervisor calls utilizing less entropy than requested.

CVE-2026-17503 [MEDIUM] CWE-20 CVE-2026-17503: IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through F IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the partition firmware runtime boot configuration. An attacker with root access to a partition can maliciously alter partition nvram, causing the partition to fail to boot. This
