If attackers exploit another vulnerability (CVE-2025-59375, rated “high”), they can block memory resources. According to the developers, AIX 7.3 and VIOS 4.1 are impacted. The developers state that python3.9.base 3.9.23.0 and python3.11.base 3.11.13.0 are equipped to handle the described attacks. So far, there are no reports of ongoing attacks.
Only recently, IBM developers resolved security issues in AIX and QRadar SIEM.
