No remote peer, packet, or RoCE traffic can drive this path.\nAC:L - On an affected adapter the out-of-bounds write happens deterministically on every stats refresh — a single `cat` of a sysfs counter or one netlink message triggers it, with no race, timing window, or memory-layout condition outside the attacker's control.\nPR:L - The `hw_counters` sysfs attributes are created with mode 0444 and `RDMA_NLDEV_CMD_STAT_GET` is registered without `RDMA_NL_ADMIN_PERM` on a `NL_CFG_F_NONROOT_RECV` socket, so any unprivileged local user can invoke the path repeatedly; only local account access is needed.\nUI:N - The attacker triggers the stats read entirely on their own by reading sysfs or sending a netlink message; no victim action is involved, and the bug also fires automatically at driver load.\nS:U - The corruption is confined to the kernel's own slab heap within the same security authority — no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a heap out-of-bounds write past a `kzalloc`'d `struct rdma_hw_stats`; such slab corruption is treated as leverageable for disclosure of adjacent kernel data, and the higher rating is chosen given the uncertainty in overflow landing.\nI:H - Four 8-byte writes land 160–191 bytes beyond the end of the 68-element `value[]` array, including a value sourced from an MMIO register — an out-of-bounds heap write, which is rated High.\nA:H - The slab-out-of-bounds write produces a KASAN BUG (as reported in the fix commit) and traps under bounds sanitization, panicking on `panic_on_warn`/UBSAN-trap kernels, and heap corruption can crash the system; an unprivileged user can retrigger it indefinitely via netlink." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/infiniband/hw/bnxt_re/hw_counters.c" ], "versions": [ { "version": "8b6573ff3420a2da1deb469a480dbc454745f784", "lessThan": "05c5fcc1869a08e36a29691699b6534e5a00a82b", "status": "affected", "versionType": "git" }, { "version": "8b6573ff3420a2da1deb469a480dbc454745f784", "lessThan": "c11b9b03ea5252898f91f3388c248f0dc47bda52", "status": "affected", "versionType": "git" }, { "version": "8b6573ff3420a2da1deb469a480dbc454745f784", "lessThan": "a9e6e7443922ac0a48243c35d03834c96926bff1", "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/infiniband/hw/bnxt_re/hw_counters.c" ], "versions": [ { "version": "6.6", "status": "affected" }, { "version": "0", "lessThan": "6.6", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.59", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.6", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "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": "6.6", "versionEndExcluding": "6.6.59" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.11.6" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/05c5fcc1869a08e36a29691699b6534e5a00a82b" }, { "url": "https://git.kernel.org/stable/c/c11b9b03ea5252898f91f3388c248f0dc47bda52" }, { "url": "https://git.kernel.org/stable/c/a9e6e7443922ac0a48243c35d03834c96926bff1" } ], "title": "RDMA/bnxt_re: Fix out of bound check", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 7.8, "attackVector": "LOCAL", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2024-50158", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "version": "2.0.3", "timestamp": "2025-10-01T20:20:30.755793Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-125", "description": "CWE-125 Out-of-bounds Read" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T20:27:12.642Z" } } ] } }
