SB2025081936 - Multiple vulnerabilities in Intel Ethernet Drivers for Linux

Description

This security bulletin contains information about 6 vulnerabilities.

1) Input validation error (CVE-ID: CVE-2025-24486)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to insufficient validation of user-supplied input in the Linux kernel-mode driver. A local user can pass specially crafted input to the application and gain elevated privileges on the target system.

2) Insufficient Control Flow Management (CVE-ID: CVE-2025-25273)

CWE-ID: CWE-691 - Insufficient Control Flow Management

CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to insufficient control flow management in the Linux kernel-mode driver. A local user can gain elevated privileges on the target system.

3) Input validation error (CVE-ID: CVE-2025-21086)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to insufficient validation of user-supplied input in the Linux kernel-mode driver. A local user can pass specially crafted input to the application and gain elevated privileges on the target system.

4) Resource exhaustion (CVE-ID: CVE-2025-26863)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in the Linux kernel-mode driver. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.

5) Resource exhaustion (CVE-ID: CVE-2025-26697)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in the Linux kernel-mode driver. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.

6) Improper Initialization (CVE-ID: CVE-2025-24511)

CWE-ID: CWE-665 - Improper Initialization

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to gain access to sensitive information on the system.

The vulnerability exists due to improper initialization in the Linux kernel-mode driver. A local user can gain access to sensitive information on the target system.
