Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: core: Run queues for all non-SDEV_DEL devices from scsi_run_host_queues While a SCSI host is in a recovery state, scsi_mq_requeue_cmd() will not set the requeue list for a requeued command to be kicked in the future. The expectation is a call to scsi_run_host_queues() will kick all SCSI devices once the recovery state is cleared. However, scsi_run_host_queues() uses shost_for_each_device() which uses scsi_device_get() and so will ignore devices in a partially removed state like SDEV_CANCEL. But these devices may also have requeued requests, leaving their requests stuck from not being kicked and causing the removal process of the device to hang. scsi_run_host_queues() needs to run against more devices than the macro shost_for_each_device() allows. Instead of using the too limiting scsi_device_get() state checks, only ignore devices in SDEV_DEL state or when unable to acquire a reference. Attempt to run the queues for all other devices when scsi_run_host_queues() is called.

the attacker acts as the remote iSCSI endpoint on an already-established session and needs no CAP_SYS_ADMIN, sysfs writes, or ioctl access.\\nUI:N - No end-user action is required during exploitation; recovery and removal are driven automatically by kernel SCSI/iSCSI error-handling once the session exists.\\nS:U - Impact is a kernel hang during SCSI device teardown on the same host; it does not cross a VM, IOMMU, or sandbox security boundary.\\nC:N - This is a queue-dispatch logic bug that leaves requeued requests stuck; there is no memory corruption, out-of-bounds access, or information disclosure.\\nI:N - The flaw prevents requeued I/O from being kicked and blocks removal completion; it does not modify data or provide a write or code-execution primitive.\\nA:H - Stuck requeued requests leave devices in SDEV_CANCEL with queues never kicked after recovery, causing the device removal path to hang indefinitely (deadlock), potentially blocking storage teardown, module unload, or shutdown.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"8b566edbdbfb5cde31a322c57932694ff48125ed\", \"lessThan\": \"15fb19af49f2073ed77fad16aaabc648b0ca6800\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8b566edbdbfb5cde31a322c57932694ff48125ed\", \"lessThan\": \"d4dddfecdbb5467bef158d4e1486459808357fef\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8b566edbdbfb5cde31a322c57932694ff48125ed\", \"lessThan\": \"475f2b37a78f4c698967a7f14f325f04e24c9175\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8b566edbdbfb5cde31a322c57932694ff48125ed\", \"lessThan\": \"c740e13e7fe32d8e4d9a1699f65b8daf6709895a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8b566edbdbfb5cde31a322c57932694ff48125ed\", \"lessThan\": \"7205b58702273baf21d6ba7992e6ba15852325f7\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/scsi/scsi_lib.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.5\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.5\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.143\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.93\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.35\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.0.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.0.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/scsi/scsi_lib.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/15fb19af49f2073ed77fad16aaabc648b0ca6800\"}, {\"url\": \"https://git.kernel.org/stable/c/d4dddfecdbb5467bef158d4e1486459808357fef\"}, {\"url\": \"https://git.kernel.org/stable/c/475f2b37a78f4c698967a7f14f325f04e24c9175\"}, {\"url\": \"https://git.kernel.org/stable/c/c740e13e7fe32d8e4d9a1699f65b8daf6709895a\"}, {\"url\": \"https://git.kernel.org/stable/c/7205b58702273baf21d6ba7992e6ba15852325f7\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nscsi: core: Run queues for all non-SDEV_DEL devices from scsi_run_host_queues\\n\\nWhile a SCSI host is in a recovery state, scsi_mq_requeue_cmd() will not\\nset the requeue list for a requeued command to be kicked in the future.\\nThe expectation is a call to scsi_run_host_queues() will kick all SCSI\\ndevices once the recovery state is cleared.\\n\\nHowever, scsi_run_host_queues() uses shost_for_each_device() which uses\\nscsi_device_get() and so will ignore devices in a partially removed\\nstate like SDEV_CANCEL.
