IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to disclose sensitive kernel memory due to an out-of-bounds read.
AnalysisAI
Kernel memory disclosure in IBM AIX 7.2 and 7.3, and IBM PowerVM VIOS 4.1 allows a local attacker with standard user privileges to read sensitive out-of-bounds kernel memory via an unspecified vulnerability. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms exploitation requires only a local shell account with no elevated rights, making it viable for any authenticated local user or a compromised service account. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local authenticated session on the affected AIX or VIOS host with at minimum standard (low-privileged) user rights, as confirmed by the CVSS vector PR:L and AV:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.5 (Medium) is consistent with the local-only attack vector and absence of integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch as documented in IBM Security Advisory at https://www.ibm.com/support/pages/node/7283858. … Detailed patch versions, workarounds, and compensating controls in full report. |
