Overview

CVE-2008-6107 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 10, 2009 and has a CVSS 2.0 base score of 4.9 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.9, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
