Linux Kernel thinkpad_acpi.c denial of service

kernel-thinkpad-dos (64580) The risk level is classified as MediumMedium Risk

Description:

Linux Kernel is vulnerable to a denial of service, caused by the failure to properly restrict access to the video output control state by the thinkpad_acpi.c. A local attacker could exploit this vulnerability using the read or write operation to cause the system to hang.

*CVSS:

Base Score: 2.1
  Access Vector: Local
  Access Complexity: Low
  Authentication: None
  Confidentiality Impact: None
  Integrity Impact: None
  Availability Impact: Partial
 
Temporal Score: 1.6
  Exploitability: Unproven
  Remediation Level: Official-Fix
  Report Confidence: Confirmed

Consequences:

Denial of Service

Remedy:

Apply the patch for this vulnerability, available from the Linux Kernel GIT Repository. See References.
