CVE-2015-8812

A use-after-free flaw was found in the CXGB3 kernel driver when the network was considered to be congested. The kernel incorrectly misinterpreted the congestion as an error condition and incorrectly freed or cleaned up the socket buffer (skb). When the device then sent the skb's queued data, these structures were referenced. A local attacker could use this flaw to panic the system (denial of service) or, with a local account, escalate their privileges.

This issue affects the Linux kernels as shipped with Red Hat Enterprise Linux 5, 6 and 7 and Red Hat Enterprise MRG 2 and realtime kernels and may be addressed in a future update.

This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates in Red Hat Enterprise Linux 5 and 6 . For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.
