IBM disclosed a large set of security vulnerabilities affecting its UNIX-based AIX operating system and the PowerVM VIOS virtualization component. The company addressed a total of 191 CVEs through multiple updated releases for both products. Thirty-five of the issues received CVSS base scores of 9.0 or higher, with three OS command injection vulnerabilities rated at 9.9 that allow remote attackers to execute commands with low privileges. IBM provided specific Technology Level and Service Pack updates for AIX 7.3 and 7.2 branches along with corresponding fixes for PowerVM VIOS versions 4.1.x. The advisory covers both IBM-developed code and third-party software components integrated into the platforms. All listed CVEs are now resolved in the recommended maintenance levels released on August 15.
