This security bulletin contains information about 1 vulnerability.


1) NULL pointer dereference (CVE-ID: CVE-2013-5634)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 5.7 [CVSS:4.0/AV:A/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the Linux kernel before 3.10 on the ARM platform, when KVM is used, allows host OS users to cause a denial of service (NULL pointer dereference, OOPS, and host OS crash) or possibly have unspecified other impact by omitting vCPU initialization before a KVM_GET_REG_LIST ioctl call. A remote attacker can perform a denial of service (DoS) attack.
