leaks/dangles objects in cq_table[], and a use-after-free on these IRQ-dispatched structures can be leveraged to read kernel memory contents.\nI:H - The driver \"goes on to corrupt the kernel,\" leaving dangling function-pointer/context entries in a table called from interrupt context, providing a write/control-flow corruption primitive.\nA:H - The user-triggerable WARN_ON panics the system

it is not exposed to network peers.\nAC:L - The condition is created entirely by the attacker (building an RWQ indirection table whose WQs share one CQ) and is deterministically triggered on the second loop iteration; there is no race or uncontrolled state.\nPR:L - Triggering only requires an unprivileged local process with access to the RDMA verbs device \u2014 the normal configuration on RDMA-enabled hosts \u2014 and no CAP_* check exists on the create-QP path.\nUI:N - The attacker performs all steps via its own verbs calls; no action by another user is required.\nS:U - The corruption stays within the kernel's own memory/security authority and does not cross a VM/IOMMU/sandbox boundary.\nC:H - The overwrite leaks/dangles objects in cq_table[], and a use-after-free on these IRQ-dispatched structures can be leveraged to read kernel memory contents.\nI:H - The driver \"goes on to corrupt the kernel,\" leaving dangling function-pointer/context entries in a table called from interrupt context, providing a write/control-flow corruption primitive.\nA:H - The user-triggerable WARN_ON panics the system when panic_on_warn is set, and the subsequent kernel state corruption causes oopses/crashes regardless."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "c15d7802a42402a87880a17eee89ff023e49ecc0", "lessThan": "9cc0c6b1ba8cd5c55aef043e1384de0a8b4efa71", "versionType": "git"}, {"status": "affected", "version": "c15d7802a42402a87880a17eee89ff023e49ecc0", "lessThan": "9ef65af26b2a6738bf15812042e84b3112402d3a", "versionType": "git"}, {"status": "affected", "version": "c15d7802a42402a87880a17eee89ff023e49ecc0", "lessThan": "db991ba50087ad99fa12a2c483aa3be19671ea73", "versionType": "git"}, {"status": "affected", "version": "c15d7802a42402a87880a17eee89ff023e49ecc0", "lessThan": "159f2efabc89d3f931d38f2d35876535d4abf0a3", "versionType": "git"}], "programFiles": ["drivers/infiniband/hw/mana/cq.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "6.8"}, {"status": "unaffected", "version": "0", "lessThan": "6.8", "versionType": "semver"}, {"status": "unaffected", "version": "6.12.91", "versionType": "semver", "lessThanOrEqual": "6.12.*"}, {"status": "unaffected", "version": "6.18.30", "versionType": "semver", "lessThanOrEqual": "6.18.*"}, {"status": "unaffected", "version": "7.0.7", "versionType": "semver", "lessThanOrEqual": "7.0.*"}, {"status": "unaffected", "version": "7.1", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["drivers/infiniband/hw/mana/cq.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/9cc0c6b1ba8cd5c55aef043e1384de0a8b4efa71"}, {"url": "https://git.kernel.org/stable/c/9ef65af26b2a6738bf15812042e84b3112402d3a"}, {"url": "https://git.kernel.org/stable/c/db991ba50087ad99fa12a2c483aa3be19671ea73"}, {"url": "https://git.kernel.org/stable/c/159f2efabc89d3f931d38f2d35876535d4abf0a3"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()\n\nSashiko points out that the user can specify WQs sharing the same CQ as a\npart of the uAPI and this will trigger the WARN_ON() then go on to corrupt\nthe kernel.\n\nJust reject it outright and fail the QP creation."}], "cpeApplicability": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "6.12.91", "versionStartIncluding": "6.8"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "6.18.30", "versionStartIncluding": "6.8"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "7.0.7", "versionStartIncluding": "6.8"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "versionEndExcluding": "7.1", "versionStartIncluding": "6.8"}], "operator": "OR"}]}], "providerMetadata": {"orgId": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "shortName": "Linux", "dateUpdated": "2026-08-05T12:29:49.531Z"}}}, "cveMetadata": {"cveId": "CVE-2026-46117", "state": "PUBLISHED", "dateUpdated": "2026-10-19T19:26:44.688Z", "dateReserved": "2026-05-13T15:03:33.098Z", "assignerOrgId": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "datePublished": "2026-05-28T09:35:32.344Z", "assignerShortName": "Linux"}, "dataVersion": "5.2"}
