Title
scsi: qla2xxx: Initialize NVMe abort_work once at submission
Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Initialize NVMe abort_work once at submission qla_nvme_fcp_abort() and qla_nvme_ls_abort() ran INIT_WORK() on priv->abort_work immediately before schedule_work(). INIT_WORK() reinitializes the work_struct, resetting its list head and clearing the pending bit. If an abort is issued more than once for the same command (for example, concurrent transport teardown and a timeout-driven abort), the second INIT_WORK() reinitializes a work item that is already queued, which can corrupt the workqueue list and lead to crashes or a looping worker. Initialize priv->abort_work once at command submission, next to the existing per-command spin_lock_init(&priv->cmd_lock), and leave only schedule_work() in the abort paths. schedule_work() already does nothing when the work item is still pending, so a repeated abort no longer disturbs an in-flight work item. The command is not returned to the transport until the final kref_put()/release callback runs after abort_work has completed, so the work item is idle before priv is reused and the single submission-time INIT_WORK() is safe.

A Fibre Channel peer (compromised NVMe-FC target or zoned SAN device) can stall commands to force timeouts and concurrently drop the link or send LOGO/RSCN so nvme_fc tears down, both of which call ls_abort/fcp_abort. FC is a non-IP fabric, so the vector is adjacent.\nAC:L - A malicious NVMe-FC target controls both sides of the documented race: delaying completions triggers timeout-driven abort while a concurrent link-down or logout triggers teardown abort. INIT_WORK() on still-queued abort_work is then attacker-influenceable under I/O load, so complexity is low.\nPR:N - The attacker is a Fibre Channel peer and needs no host credentials or capabilities. Fabric zoning/WWPN is a topology restriction captured by Adjacent, not an OS privilege, and NVMe in-band authentication is optional and off by default.\nUI:N - With ql2xnvmeenable defaulting to on, an established NVMe-FC association issues keepalives and I/O without user action. The target can stall those commands and flap the link without anyone mounting a volume or running a tool.\nS:U - Impact is kernel workqueue list corruption in the same host kernel that runs qla2xxx. That is ordinary kernel memory-corruption impact, not a VM escape, IOMMU bypass, or other crossed security authority.\nC:H - INIT_WORK() on a queued work_struct resets its list head without unlinking it, corrupting the workqueue and creating a use-after-free of work items. That UAF can be used to read kernel memory, so confidentiality is high.\nI:H - The same workqueue UAF can overwrite adjacent objects and hijack work-\u003efunc when the worker runs a freed item, yielding an arbitrary-write / control-flow primitive, so integrity is high.\nA:H - The corrupted workqueue can oops, panic, or run a looping worker, crashing or hanging the kernel, so availability is high."

INIT_WORK()\\nreinitializes the work_struct, resetting its list head and clearing the\\npending bit. If an abort is issued more than once for the same command\\n(for example, concurrent transport teardown and a timeout-driven abort),\\nthe second INIT_WORK() reinitializes a work item that is already queued,\\nwhich can corrupt the workqueue list and lead to crashes or a looping\\nworker.\\n\\nInitialize priv-\u003eabort_work once at command submission, next to the\\nexisting per-command spin_lock_init(\u0026priv-\u003ecmd_lock), and leave only\\nschedule_work() in the abort paths. schedule_work() already does nothing\\nwhen the work item is still pending, so a repeated abort no longer\\ndisturbs an in-flight work item. The command is not returned to the\\ntransport until the final kref_put()/release callback runs after\\nabort_work has completed, so the work item is idle before priv is reused\\nand the single submission-time INIT_WORK() is safe.\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"drivers/scsi/qla2xxx/qla_nvme.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"e473b3074104ee09227cfbba5f872e3ea15dd280\",\"lessThan\":\"b403700ac62fbf3c310196386e125879a182efcf\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"e473b3074104ee09227cfbba5f872e3ea15dd280\",\"lessThan\":\"6a1b50c4879c2e6a034e8e85f9c055f0eea157c7\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"e473b3074104ee09227cfbba5f872e3ea15dd280\",\"lessThan\":\"67f0d5187c29360388f7e1e503c627ec45d01089\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"e473b3074104ee09227cfbba5f872e3ea15dd280\",\"lessThan\":\"f4aaa4a4e6f1da6f3abfd80e1917bef922287177\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"e473b3074104ee09227cfbba5f872e3ea15dd280\",\"lessThan\":\"7e85f6dbc85616de2172bce8eaf84b387a723cd1\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"drivers/scsi/qla2xxx/qla_nvme.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"4.17\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"4.17\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.6.157\",\"lessThanOrEqual\":\"6.6.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12.110\",\"lessThanOrEqual\":\"6.12.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.18.51\",\"lessThanOrEqual\":\"6.18.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.2.5\",\"lessThanOrEqual\":\"7.2.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.3-rc1\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\",\"baseScore\":8.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"ADJACENT_NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.8,\"impactScore\":5.9}]},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/67f0d5187c29360388f7e1e503c627ec45d01089\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/6a1b50c4879c2e6a034e8e85f9c055f0eea157c7\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/7e85f6dbc85616de2172bce8eaf84b387a723cd1\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/b403700ac62fbf3c310196386e125879a182efcf\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/f4aaa4a4e6f1da6f3abfd80e1917bef922287177\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"}]}}"
