High CVSS 8.8

CVE-2026-16932

Ibm Vios

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to execute arbitrary commands due to improper validation of the ODMDIR environment variable.

What this means

Exposure
Exploitable with local access to the machine, with an ordinary user account and with no action from the victim.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
Weakness
Unfiltered input reaches the system shell, letting the attacker run their own commands on the server.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
