Complexity

34%

Confidentiality

165%

Per: http://cwe.mitre.org/data/definitions/476.html 'CWE-476: NULL Pointer Dereference'

mm/shmem.c in the Linux kernel before 2.6.28-rc3, when strict overcommit is enabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors.

Per: http://cwe.mitre.org/data/definitions/476.html 'CWE-476: NULL Pointer Dereference'

CVSS 2.0 Base Score 6.9. CVSS Attack Vector: local. CVSS Attack Complexity: medium. CVSS Vector: (AV:L/AC:M/Au:N/C:C/I:C/A:C).
