Yet, it can occur\nto SMMU too, since arm_smmu_mm_arch_invalidate_secondary_tlbs() is called\ntypically next to MMU tlb flush function, e.g.\n\ttlb_flush_mmu_tlbonly {\n\t\ttlb_flush {\n\t\t\t__flush_tlb_range {\n\t\t\t\t// check MAX_TLBI_OPS\n\t\t\t}\n\t\t}\n\t\tmmu_notifier_arch_invalidate_secondary_tlbs {\n\t\t\tarm_smmu_mm_arch_invalidate_secondary_tlbs {\n\t\t\t\t// does not check MAX_TLBI_OPS\n\t\t\t}\n\t\t}\n\t}\n\nClone a CMDQ_MAX_TLBI_OPS from the MAX_TLBI_OPS in tlbflush.h, since in an\nSVA case SMMU uses the CPU page table, so it makes sense to align with the\ntlbflush code. Then, replace per-page TLBI commands with a single per-asid\nTLBI command, if the request size hits this threshold." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3-sva.c" ], "versions": [ { "version": "51d113c3be09ff5b916576b1109daf413549cacc", "lessThan": "f5a604757aa8e37ea9c7011dc9da54fa1b30f29b", "status": "affected", "versionType": "git" }, { "version": "51d113c3be09ff5b916576b1109daf413549cacc", "lessThan": "f90f4c562003ac3d3b135c5a40a5383313f27264", "status": "affected", "versionType": "git" }, { "version": "51d113c3be09ff5b916576b1109daf413549cacc", "lessThan": "3283a1bce9bbc978059f790b84f3c10c32492429", "status": "affected", "versionType": "git" }, { "version": "51d113c3be09ff5b916576b1109daf413549cacc", "lessThan": "d5afb4b47e13161b3f33904d45110f9e6463bad6", "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/iommu/arm/arm-smmu-v3/arm-smmu-v3-sva.c" ], "versions": [ { "version": "5.12", "status": "affected" }, { "version": "0", "lessThan": "5.12", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.134", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.56", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.5.6", "lessThanOrEqual": "6.5.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6", "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": "5.15.134" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.12", "versionEndExcluding": "6.1.56" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.12", "versionEndExcluding": "6.5.6" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.12", "versionEndExcluding": "6.6" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/f5a604757aa8e37ea9c7011dc9da54fa1b30f29b" }, { "url": "https://git.kernel.org/stable/c/f90f4c562003ac3d3b135c5a40a5383313f27264" }, { "url": "https://git.kernel.org/stable/c/3283a1bce9bbc978059f790b84f3c10c32492429" }, { "url": "https://git.kernel.org/stable/c/d5afb4b47e13161b3f33904d45110f9e6463bad6" } ], "title": "iommu/arm-smmu-v3: Fix soft lockup triggered by arm_smmu_mm_invalidate_range", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CISA ADP Vulnrichment", "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2023-52484", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-03-04T20:38:22.448453Z" } } } ], "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-04T17:22:37.470Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T23:03:19.772Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/f5a604757aa8e37ea9c7011dc9da54fa1b30f29b", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/f90f4c562003ac3d3b135c5a40a5383313f27264", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/3283a1bce9bbc978059f790b84f3c10c32492429", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/d5afb4b47e13161b3f33904d45110f9e6463bad6", "tags": [ "x_transferred" ] } ] } ] } }
