ISS X-Force Database: linux-kernel-cifscreate-dos(57561): Linux Kernel cifs

Linux Kernel cifs_create() function denial of service

linux-kernel-cifscreate-dos (57561)

Medium Risk

Description:

Linux Kernel is vulnerable to a denial of service, caused by NULL pointer dereference error in the cifs_create() function. A local attacker could exploit this vulnerability to cause the system to crash.

*CVSS:

Base Score:	4.9
Access Vector:	Local
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Complete

Temporal Score:	3.6
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

Apply the patch for this vulnerability (b/fs/cifs/cifsproto.h), available from the Linux Kernel GIT Repository. See References.

For other distributions:
Apply the appropriate update for your system. See References.
