Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix potential panic dues to unprotected smc_llc_srv_add_link()
There is a certain chance to trigger the following panic:

#9 [ffff9456c1cc7ce0] __smc_buf_create at ffffffffc0b03586 [smc]
The reason here is that when the server tries to create a second link,
smc_llc_srv_add_link() has no protection and may add a new link to
link group. This breaks the security environment protected by
llc_conf_mutex.
