NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-container package and not the kernel-uek-container package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

sunrpc: clear XPRT_SOCK_UPD_TIMEOUT when reset transport

Since transport->sock has been set to NULL during reset transport, XPRT_SOCK_UPD_TIMEOUT also needs to be cleared. Otherwise, the xs_tcp_set_socket_timeouts() may be triggered in xs_tcp_send_request() to dereference the transport->sock that has been set to NULL.
