      "title": "net: dsa: mxl862xx: fix use-after-free of DSA ports in crc_err_work",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: mxl862xx: fix use-after-free of DSA ports in crc_err_work\n\nUpon an MDIO CRC error mxl862xx_crc_err_work_fn() walks the DSA ports\nand closes the CPU port conduits:\n\n\tdsa_switch_for_each_cpu_port(dp, priv->ds)\n\t\tdev_close(dp->conduit);\n\nmxl862xx_remove() unregisters the switch before cancelling this work:\n\n\tset_bit(MXL862XX_FLAG_WORK_STOPPED, &priv->flags);\n\tcancel_delayed_work_sync(&priv->stats_work);\n\tdsa_unregister_switch(ds);\n\tmxl862xx_host_shutdown(priv);\n\ndsa_unregister_switch() frees the dsa_port objects. If a CRC error\nschedules the work during teardown it can run after the ports have been\nfreed and dereference freed memory.\n\nGuard the port walk with MXL862XX_FLAG_WORK_STOPPED, which is already set\nbefore dsa_unregister_switch(). DSA tears the ports down under\nrtnl_lock(), so checking the flag under rtnl_lock() means the work either\nruns before teardown and sees valid ports, or runs afterwards, observes\nthe flag and skips the walk. This mirrors the host_flood_work handler,\nwhich skips torn-down ports under rtnl_lock().",
