Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2025-41236)
The vulnerability allows an attacker to compromise the host OS.
The vulnerability exists due to integer overflow in the VMXNET3 virtual network adapter. A malicious guest with administrative privileges can trigger an integer overflow and execute arbitrary code on the host OS.
2) Integer underflow (CVE-ID: CVE-2025-41237)
The vulnerability allows an attacker to compromise the affected host OS.
The vulnerability exists due to integer underflow in VMCI (Virtual Machine Communication Interface). A malicious guest with local administrative privileges on a virtual machine can trigger an integer underflow and execute arbitrary code as the virtual machine's VMX process running on the host.
3) Heap-based buffer overflow (CVE-ID: CVE-2025-41238)
The vulnerability allows an attacker to compromise the host OS.
The vulnerability exists due to a boundary error in the PVSCSI (Paravirtualized SCSI) controller. A malicious guest with local administrative privileges on a virtual machine can trigger a heap-based buffer overflow and execute arbitrary code as the virtual machine's VMX process running on the host.
4) Memory leak (CVE-ID: CVE-2025-41239)
The vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists due memory leak in vSockets. A malicious guest with local administrative privileges on a virtual machine can leak memory from processes communicating with vSockets.
5) Input validation error (CVE-ID: CVE-2025-41226)
The vulnerability allows a remote guest to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote guest can perform a denial of service attack against other guest VMs with VMware Tools running and guest operations enabled.
6) Resource exhaustion (CVE-ID: CVE-2025-41227)
The vulnerability allows a malicious guest to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A malicious guest can trigger resource exhaustion of the host process.
7) Cross-site scripting (CVE-ID: CVE-2025-41228)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
