"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: core: pair EH runtime PM get and put\n\nshost->eh_noresume is currently consulted twice in one error handling\niteration: once before scsi_autopm_get_host() and once again before\nscsi_autopm_put_host().\n\nThat is racy when a PM-triggered error path flips shost->eh_noresume\nwhile the SCSI EH thread is still running.\n\nThe problem flow looks like this:\nPM path\n ufshcd_set_dev_pwr_mode()\n shost->eh_noresume = 1\n ufshcd_execute_start_stop <-- trigger EH\n ...\n shost->eh_noresume = 0\n\nEH path\n scsi_error_handler()\n if (!shost->eh_noresume)\n scsi_autopm_get_host() <-- skipped\n ...\n if (!shost->eh_noresume)\n scsi_autopm_put_host() <-- executed later\n\nIn that case one EH iteration can skip autoresume on entry and still\ndrop a runtime PM reference on exit. That leaves an unmatched runtime PM\nput and can trigger a runtime PM usage count underflow.\n\nFix this by making eh_noresume a regular bool so it can be accessed with\nREAD_ONCE() and WRITE_ONCE(). Snapshot it once per EH iteration and use\nthat snapshot for both runtime PM get and put decisions."
