INIT_WORK()\nreinitializes the work_struct, resetting its list head and clearing the\npending bit.

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->func 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." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/scsi/qla2xxx/qla_nvme.c" ], "versions": [ { "version": "e473b3074104ee09227cfbba5f872e3ea15dd280", "lessThan": "b403700ac62fbf3c310196386e125879a182efcf", "status": "affected", "versionType": "git" }, { "version": "e473b3074104ee09227cfbba5f872e3ea15dd280", "lessThan": "6a1b50c4879c2e6a034e8e85f9c055f0eea157c7", "status": "affected", "versionType": "git" }, { "version": "e473b3074104ee09227cfbba5f872e3ea15dd280", "lessThan": "67f0d5187c29360388f7e1e503c627ec45d01089", "status": "affected", "versionType": "git" }, { "version": "e473b3074104ee09227cfbba5f872e3ea15dd280", "lessThan": "f4aaa4a4e6f1da6f3abfd80e1917bef922287177", "status": "affected", "versionType": "git" }, { "version": "e473b3074104ee09227cfbba5f872e3ea15dd280", "lessThan": "7e85f6dbc85616de2172bce8eaf84b387a723cd1", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/scsi/qla2xxx/qla_nvme.c" ], "versions": [ { "version": "4.17", "status": "affected" }, { "version": "0", "lessThan": "4.17", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.157", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.110", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.51", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.2.5", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.3", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.17", "versionEndExcluding": "6.6.157" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.17", "versionEndExcluding": "6.12.110" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.17", "versionEndExcluding": "6.18.51" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.17", "versionEndExcluding": "7.2.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.17", "versionEndExcluding": "7.3" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/b403700ac62fbf3c310196386e125879a182efcf" }, { "url": "https://git.kernel.org/stable/c/6a1b50c4879c2e6a034e8e85f9c055f0eea157c7" }, { "url": "https://git.kernel.org/stable/c/67f0d5187c29360388f7e1e503c627ec45d01089" }, { "url": "https://git.kernel.org/stable/c/f4aaa4a4e6f1da6f3abfd80e1917bef922287177" }, { "url": "https://git.kernel.org/stable/c/7e85f6dbc85616de2172bce8eaf84b387a723cd1" } ], "title": "scsi: qla2xxx: Initialize NVMe abort_work once at submission", "x_generator": { "engine": "bippy-1.2.0" } } } }
