The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state.

Patch is available. (Score: 7.8high / local)

File affected: kernel-adaptation-sbj-3.4.108.20161101.1/net/dccp/proto.c lines 252-256; 271-276
