Technical Description

A vulnerability has been identified in Linux Kernel, which could be exploited by remote attackers to take complete control of an affected system or cause a denial of service. This flaw is due to buffer overflow errors in the "cmtp_recv_interopmsg()" [net/bluetooth/cmtp/capi.c] function when handling malformed CAPI packets, which could be exploited by attackers to overwrite internal CMTP and CAPI data structures and execute arbitrary commands with elevated privileges.
