      "title": "net/smc: Avoid overwriting the copies of clcsock callback functions",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: Avoid overwriting the copies of clcsock callback functions\n\nThe callback functions of clcsock will be saved and replaced during\nthe fallback. But if the fallback happens more than once, then the\ncopies of these callback functions will be overwritten incorrectly,\nresulting in a loop call issue:\n\nclcsk->sk_error_report\n |- smc_fback_error_report() <------------------------------|\n     |- smc_fback_forward_wakeup()                          | (loop)\n         |- clcsock_callback()  (incorrectly overwritten)   |\n             |- smc->clcsk_error_report() ------------------|\n\nSo this patch fixes the issue by saving these function pointers only\nonce in the fallback and avoiding overwriting.",
