CVE-2026-19492 3.2 Faible
IBM PowerVM Hypervisor · Ibm power system s1122 \(9824-22a\) firmware · Ibm power system s1124 \(9824-42a\) firmware · Ibm power system s1122s \(9824-22b\) firmware
IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, and FW1060.00 through FW1060.81 is affected by a vulnerability in a hypervisor call interface. An attacker with root access to a guest partition can read a limited amount of hypervisor memory, potentially exposing sensitive data belonging to the hypervisor or other guest partitions hosted on the same system, resulting in a confidentiality impact. The attacker has no control over which memory contents are returned. This vulnerability is of particular concern in multi-tenant environments where guests may run arbitrary OS images.

CVE-2026-18870 4.3 Moyenne
IBM PowerVM Hypervisor · Ibm power system s1122 \(9824-22a\) firmware · Ibm power system s1124 \(9824-42a\) firmware · Ibm power system s1122s \(9824-22b\) firmware
IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 could allow a remote attacker to obtain sensitive information due to an out-of-bounds read.

CVE-2026-17511 3.4 Faible
IBM PowerVM Hypervisor · Ibm power system s1122 \(9824-22a\) firmware · Ibm power system s1124 \(9824-42a\) firmware · Ibm power system s1122s \(9824-22b\) firmware
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 resource dump interface. An attacker with authenticated administrator-level access to the HMC or service processor can obtain a limited snapshot of partition processor state. Successful exploitation results in a confidentiality impact to the managed system.

CVE-2026-17504 4.4 Moyenne
IBM PowerVM Hypervisor · Ibm power system s1122 \(9824-22a\) firmware · Ibm power system s1124 \(9824-42a\) firmware · Ibm power system s1122s \(9824-22b\) firmware
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. An attacker with root access to a partition can send a specially crafted request to the partition firmware runtime, causing it to crash with possible memory corruption.

CVE-2026-17503 5.1 Moyenne
IBM PowerVM Hypervisor · Ibm power system s1122 \(9824-22a\) firmware · Ibm power system s1124 \(9824-42a\) firmware · Ibm power system s1122s \(9824-22b\) firmware
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 condition persists until operator intervention — deleting and recreating the partition configuration — to restore normal operation. Successful exploitation results in an integrity and availability impact.

CVE-2026-17413 5.1 Moyenne
IBM PowerVM Hypervisor · Ibm power system s1122 \(9824-22a\) firmware · Ibm power system s1124 \(9824-42a\) firmware · Ibm power system s1122s \(9824-22b\) firmware
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 the partition to crash and become unavailable. Other partitions on the same managed system are not affected.
