High CVSS 8.8

CVE-2026-16848

Ibm Aix

IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to execute arbitrary commands due to improper neutralization of shell metacharacters in DHCP options.

What this means

Exposure
Exploitable from the adjacent network, without authentication and with no action from the victim.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
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.

What to doFold into the next patch cycle.
