VMware released security updates to fix critical sandbox escape vulnerabilities in VMware ESXi, Workstation, Fusion, and Cloud Foundation products, allowing attackers to escape virtual machines and access the host operating system.
These types of flaws are critical as they could permit attackers to gain unauthorized access to the host system where a hypervisor is installed or access other virtual machines running on the same host, breaching their isolation.
CVE-2024-22254: Out-of-bounds write flaw in ESXi, allowing an attacker with VMX process privileges to write outside the pre-determined memory region, potentially leading to sandbox escape.
CVE-2024-22255: Information disclosure problem in the UHCI USB controller impacting ESXi, Workstation, and Fusion.
It is worth noting that VMware has made security fixes available for older ESXi versions, 6.5, and VCF 3.x due to the vulnerabilities' severity.
VMware has neither observed nor received any reports indicating active exploitation of the four flaws.
