CVE-2017-11600

High
Published: Translated: NVD NIST

Summary

In the Linux kernel up to version 4.12.3, when CONFIG_XFRM_MIGRATE is enabled, the dir value of xfrm_userpolicy_id is not ensured to be XFRM_POLICY_MAX or less. This can lead to denial of service (out-of-bounds access) or possibly other unspecified impacts via an XFRM_MSG_MIGRATE xfrm Netlink message.

Risk Assessment

Local users may exploit this vulnerability to cause a denial of service, impacting system availability. There is also a risk of unspecified impacts that could affect data integrity and confidentiality.

Recommendation

It is recommended to update the Linux kernel to a version that is not vulnerable to this issue. Consider disabling the CONFIG_XFRM_MIGRATE option if it is not necessary.
