SRP supports RDMA CM with IP destinations (RoCEv2/iWARP), so a malicious or compromised target can reach the vulnerable path across an L3/IP network.\nAC:L - A malicious target can induce SCSI timeouts (triggering srp_abort/srp_claim_req) by withholding completions, then send the delayed SRP_RSP to hit the claim-failed window, so the attacker controls both sides of the race.\nPR:N - Exploitation is performed by the remote SRP target peer sending RDMA responses; no privileges on the victim initiator host are required once an administrator has already established the SRP session.\nUI:N - No additional user action is needed at exploit time; the crash occurs on the IRQ/softirq receive completion path during an already-configured SRP session.\nS:U - Impact is a kernel oops in the initiator's own kernel security authority, with no VM escape, IOMMU bypass, or other cross-boundary effect.\nC:N - This is a pure NULL pointer write dereference (scmnd->result at NULL+offset) that faults without disclosing kernel memory.\nI:N - The faulting store never successfully corrupts kernel state under normal mmap_min_addr protections; there is no usable write primitive beyond the crash.\nA:H - The NULL dereference causes a kernel oops/crash (as shown in the reported srp_recv_done oops), fully impacting availability." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/infiniband/ulp/srp/ib_srp.c" ], "versions": [ { "version": "81982125c352f2db1012c2cd37487e6c0c3b7da8", "lessThan": "f022576aa03c2385ea7f2b27ee5b331e43abf624", "status": "affected", "versionType": "git" }, { "version": "ad215aaea4f9d637f441566cdbbc610e9849e1fa", "lessThan": "a8edd49c94b4b08019ed7d6dd794fca8078a4deb", "status": "affected", "versionType": "git" }, { "version": "ad215aaea4f9d637f441566cdbbc610e9849e1fa", "lessThan": "f2c70f56f762e5dc3b0d7dc438fbb137cb116413", "status": "affected", "versionType": "git" }, { "version": "ad215aaea4f9d637f441566cdbbc610e9849e1fa", "lessThan": "12f35199a2c0551187edbf8eb01379f0598659fa", "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/ulp/srp/ib_srp.c" ], "versions": [ { "version": "5.14", "status": "affected" }, { "version": "0", "lessThan": "5.14", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.68", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.19.9", "lessThanOrEqual": "5.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.0", "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": "5.14", "versionEndExcluding": "5.15.68" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.14", "versionEndExcluding": "5.19.9" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.14", "versionEndExcluding": "6.0" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/f022576aa03c2385ea7f2b27ee5b331e43abf624" }, { "url": "https://git.kernel.org/stable/c/a8edd49c94b4b08019ed7d6dd794fca8078a4deb" }, { "url": "https://git.kernel.org/stable/c/f2c70f56f762e5dc3b0d7dc438fbb137cb116413" }, { "url": "https://git.kernel.org/stable/c/12f35199a2c0551187edbf8eb01379f0598659fa" } ], "title": "RDMA/srp: Set scmnd->result only when scmnd is not NULL", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-03T15:17:55.719Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/f022576aa03c2385ea7f2b27ee5b331e43abf624", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/a8edd49c94b4b08019ed7d6dd794fca8078a4deb", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/f2c70f56f762e5dc3b0d7dc438fbb137cb116413", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/12f35199a2c0551187edbf8eb01379f0598659fa", "tags": [ "x_transferred" ] } ] }, { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2022-48692", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-09-10T15:43:36.035080Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-11T17:33:27.772Z" } } ] } }
