Description
This security bulletin contains information about 7 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2025-41236)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:L/VA:L/SC:H/SI:H/SA:H/E:U/U:Green
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)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:H/SI:H/SA:H/E:U/U:Green
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)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Green
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)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:H/E:U/U:Green
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)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L/E:U/U:Green
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)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
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.
