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"]}]}]}}
