CVE-2023-5633 is a high-severity use-after-free vulnerability in Red Hat Enterprise Linux 8 that arises from reference count changes made during previous fixes (CVE-2023-33951 and CVE-2023-33952). It affects systems running as VMware guests with 3D acceleration enabled. A local, unprivileged user could exploit this flaw to escalate privileges without requiring user interaction. The vulnerability impacts confidentiality, integrity, and availability, with a CVSS score of 7.8. No known exploits are currently reported in the wild. European organizations using RHEL 8 in VMware virtualized environments with 3D acceleration enabled are at risk, especially those in countries with high adoption of Red Hat and VMware technologies. Mitigation requires applying vendor patches promptly and disabling 3D acceleration in VMware guests if patching is delayed. Additional hardening of local user privileges and monitoring for unusual privilege escalation attempts is recommended.
