| Description |
| + |
A use-after-free vulnerability was found in DCCP socket code affecting the Linux kernel since 2.6.16. The dccp_disconnect function in net/dccp/proto.c allows local users to gain privileges or cause a denial of service via an AF_UNSPEC connect system call during the DCCP_LISTEN state. |

| Notes |
| + |
On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: |

echo >> /etc/modprobe.d/disable-dccp.conf install dccp false |
