  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: fix UAF on lgr list traversal in smcr_port_err()\n\nsmcr_port_err() traverses smc_lgr_list.list without holding\nsmc_lgr_list.lock, allowing a concurrent smc_lgr_terminate_sched()\nto free an lgr while it is still being dereferenced.\n\nHold smc_lgr_list.lock across the traversal. Update\nsmc_ib_gid_check() to call smcr_port_err() after releasing the lock.",
