CVE-2017-1000111

Description

A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. In a default or common use of Red Hat Enterprise Linux 6 and 7 this issue does not allow an unprivileged local user elevate their privileges on the system. In order to exploit this issue the attacker needs CAP_NET_RAW capability, which needs to be granted by the administrator to the attacker\'s account. Since Red Hat Enterprise Linux does not have unprivileged user namespaces enabled by default, local unprivileged users also cannot abuse namespaces to grant this capability to themselves and elevate their privileges.
