Description

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) over InfiniBand (IB) connection teardown process. When the rds_ib_setup_qp() function fails to set up a connection, it may free a memory allocation (i_sends) without properly clearing the associated pointer. This can lead to a stale pointer being used in a subsequent shutdown operation, potentially causing incorrect memory access and system instability or a denial of service.
