Linux Kernel virtual address denial of service

linux-kernel-virtual-address-dos (48710) The risk level is classified as MediumMedium Risk

Description:

Linux Kernel is vulnerable to a denial of service, caused by the improper validation of re-mapped virtual address ranges by the sys32_mremap, sparc_mmap_check and sparc64_mmap_check functions when the mremap MREMAP_FIXED bit is disabled. By sending unspecified mremap calls, a local attacker could exploit this vulnerability to cause a system panic.

*CVSS:

Base Score: 1.9
  Access Vector: Local
  Access Complexity: Medium
  Authentication: None
  Confidentiality Impact: None
  Integrity Impact: None
  Availability Impact: Partial
 
Temporal Score: 1.4
  Exploitability: Unproven
  Remediation Level: Official-Fix
  Report Confidence: Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of Linux Kernel (2.6.25.4 or later), available from The Linux Kernel Archives Web site. See References.

  • CVE-2008-6107: The (1) sys32_mremap function in arch/sparc64/kernel/sys_sparc32.c, the (2) sparc_mmap_check function in arch/sparc/kernel/sys_sparc.c, and the (3) sparc64_mmap_check function in arch/sparc64/kernel/sys_sparc.c, in the Linux kernel before 2.6.25.4, omit some virtual-address range (aka span) checks when the mremap MREMAP_FIXED bit is not set, which allows local users to cause a denial of service (panic) via unspecified mremap calls, a related issue to CVE-2008-2137.
