NVMe-oF host/target sessions are ordinary network protocol exchanges, matching the treatment of other nvme fabrics host-side flaws.\nAC:L - The target only has to advertise a non-zero icdoff or clear NVME_CTRL_SGLS_KSDBDS to deterministically force the host into the destroy_admin path, and any admin request left undispatched on the quiesced queue makes the freeze wait forever. The attacker can also re-drive controller creation repeatedly via discovery-log-change AENs, so no condition outside their control must happen to line up.\nPR:N - The attacker is the remote peer and needs no credentials on the victim host \u2014 NVMe-oF requires no mandatory authentication, and there is no capable() check anywhere on the nvmf_dev_write \u2192 nvme_rdma_setup_ctrl path. The host-side privileged action is performed by the system's own autoconnect tooling, not by the attacker.\nUI:N - On hosts configured for NVMe-oF, systemd/udev autoconnect creates controllers (new=true) automatically in response to discovery-log-change AENs from the target, so no human action is needed at exploitation time.\nS:U - The hang is confined to the kernel's own block/NVMe layer and the calling process; no security authority or isolation boundary is crossed.\nC:N - The defect is a missing unquiesce leading to an indefinite wait in blk_mq_freeze_queue_wait(); no freed or out-of-bounds memory is read and nothing is disclosed to the attacker.\nI:N - There is no memory corruption, no write primitive, and no unintended state modification \u2014 the queue simply never drains, so no data can be altered.\nA:H - The calling task blocks forever in TASK_UNINTERRUPTIBLE and is unkillable, holding nvmf_dev_mutex so every later /dev/nvme-fabrics operation on the system wedges too, pinning the module and preventing clean shutdown; the hung-task watchdog fires and panics the box when hung_task_panic is set."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/nvme/host/rdma.c"], "versions": [{"version": "958dc1d32c80566f58d18f05ef1f05bd32d172c1", "lessThan": "53bdbe5dc80b5887af51d62bf44e50f56972db5f", "status": "affected", "versionType": "git"}, {"version": "958dc1d32c80566f58d18f05ef1f05bd32d172c1", "lessThan": "427036030f4d796533dcadba9b845896cb6c10a7", "status": "affected", "versionType": "git"}, {"version": "958dc1d32c80566f58d18f05ef1f05bd32d172c1", "lessThan": "05b436f3cf65c957eff86c5ea5ddfa2604b32c63", "status": "affected", "versionType": "git"}, {"version": "958dc1d32c80566f58d18f05ef1f05bd32d172c1", "lessThan": "5858b687559809f05393af745cbadf06dee61295", "status": "affected", "versionType": "git"}, {"version": "a9ea34d2717a8c8892d3c5677329de9485e325ac", "status": "affected", "versionType": "git"}, {"version": "7da81eaf8710130a9e63d7429627183be5a93787", "status": "affected", "versionType": "git"}, {"version": "caed0b3851a4f52afd1ef77a27b30410fe7b68c7", "status": "affected", "versionType": "git"}, {"version": "5.4.103", "lessThan": "5.5", "status": "affected", "versionType": "semver"}, {"version": "5.10.21", "lessThan": "5.11", "status": "affected", "versionType": "semver"}, {"version": "5.11.4", "lessThan": "5.12", "status": "affected", "versionType": "semver"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/nvme/host/rdma.c"], "versions": [{"version": "5.12", "status": "affected"}, {"version": "0", "lessThan": "5.12", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.191", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.88", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.5", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.13", "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": "5.12", "versionEndExcluding": "6.1.191"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.12", "versionEndExcluding": "6.6.88"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.12", "versionEndExcluding": "6.12.5"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.12", "versionEndExcluding": "6.13"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.4.103"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10.21"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11.4"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/53bdbe5dc80b5887af51d62bf44e50f56972db5f"}, {"url": "https://git.kernel.org/stable/c/427036030f4d796533dcadba9b845896cb6c10a7"}, {"url": "https://git.kernel.org/stable/c/05b436f3cf65c957eff86c5ea5ddfa2604b32c63"}, {"url": "https://git.kernel.org/stable/c/5858b687559809f05393af745cbadf06dee61295"}], "title": "nvme-rdma: unquiesce admin_q before destroy it", "x_generator": {"engine": "bippy-1.2.0"}}}}
