CVE-2015-4692

CVSS v2.0

4.9

Medium

VectorAV:L/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions through 4.1.3
Description The issue allows local users to cause a denial of service, resulting in a system crash due to a NULL pointer dereference. This is achieved by leveraging access to /dev/kvm for an ioctl call, potentially having other unspecified impacts. The estimated number of potentially affected devices and details about real-world incidents are not provided.
Recommendations For Linux kernel versions through 4.1.3, update to a version later than 4.1.3 to resolve the issue. As a temporary workaround, consider restricting access to /dev/kvm to minimize the risk of exploitation.
