The vulnerability of the MPTCP protocol implementation in Linux kernel’s mptcp_copy_inaddrs() function allows a attacker to cause a service failure.

The vulnerability in the implementation of the MPTCP protocol in Linux kernel relates to the assignment of a zero pointer in the function mptcpcopyinaddrs in the net/mptcp/protocol.c module, during the processing of the list of nested threads when disabling them. Exploiting this vulnerability can...
