Описание
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix UAF on lgr list traversal in smcr_port_err()
smcr_port_err() traverses smc_lgr_list.list without holding smc_lgr_list.lock, allowing a concurrent smc_lgr_terminate_sched() to free an lgr while it is still being dereferenced.
Hold smc_lgr_list.lock across the traversal. Update smc_ib_gid_check() to call smcr_port_err() after releasing the lock.
