The bug is reached only through the local `perf_event_open(2)` syscall against a HiSilicon PCIe PMU device; no network or remote-peer data is involved.\nAC:L - Triggering is fully deterministic — open a group leader plus 7 distinct hisi_pcie events, then open a 9th distinct event — with no race, timing window, or memory-layout condition outside the attacker's control.\nPR:L - On the profiling/HPC/Kunpeng-server deployments where this PMU driver is actually used, `kernel.perf_event_paranoid` is commonly set to 0 or -1, which makes `perf_allow_cpu()` pass for any unprivileged local user; only that (not real root) is needed to build the oversized event group.\nUI:N - The attacker performs the entire nine-syscall sequence itself; no victim action or cooperation is required.\nS:U - The out-of-bounds write corrupts the kernel's own stack within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The overflow is stack memory corruption adjacent to saved registers and spilled pointers, which per kernel scoring practice can be leveraged toward disclosure of kernel memory and defeats stack-layout confidentiality assumptions.\nI:H - This is an out-of-bounds stack write that places an attacker-groomed kernel heap pointer over the canary/saved-register slot above the array, i.e. corruption of control-flow-relevant stack state.\nA:H - On stack-protector-enabled arm64 builds the OOB write clobbers the canary and reliably triggers `__stack_chk_fail()` → kernel panic, and it can be repeated at will from userspace." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/perf/hisilicon/hisi_pcie_pmu.c" ], "versions": [ { "version": "8404b0fbc7fbd42e5c5d28cdedd450e70829c77a", "lessThan": "3d1face00ebb7996842aee4214d7d0fb0c77b1e9", "status": "affected", "versionType": "git" }, { "version": "8404b0fbc7fbd42e5c5d28cdedd450e70829c77a", "lessThan": "8e9aab2492178f25372f1820bfd9289fbd74efd0", "status": "affected", "versionType": "git" }, { "version": "8404b0fbc7fbd42e5c5d28cdedd450e70829c77a", "lessThan": "567d34626c22b36579ec0abfdf5eda2949044220", "status": "affected", "versionType": "git" }, { "version": "8404b0fbc7fbd42e5c5d28cdedd450e70829c77a", "lessThan": "ff48247144d13a3a0817127703724256008efa78", "status": "affected", "versionType": "git" }, { "version": "8404b0fbc7fbd42e5c5d28cdedd450e70829c77a", "lessThan": "77fce82678ea5fd51442e62febec2004f79e041b", "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/perf/hisilicon/hisi_pcie_pmu.c" ], "versions": [ { "version": "5.17", "status": "affected" }, { "version": "0", "lessThan": "5.17", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.93", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.33", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.12", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9.3", "lessThanOrEqual": "6.9.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10", "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": "5.17", "versionEndExcluding": "6.1.93" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.6.33" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.8.12" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.9.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.10" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/3d1face00ebb7996842aee4214d7d0fb0c77b1e9" }, { "url": "https://git.kernel.org/stable/c/8e9aab2492178f25372f1820bfd9289fbd74efd0" }, { "url": "https://git.kernel.org/stable/c/567d34626c22b36579ec0abfdf5eda2949044220" }, { "url": "https://git.kernel.org/stable/c/ff48247144d13a3a0817127703724256008efa78" }, { "url": "https://git.kernel.org/stable/c/77fce82678ea5fd51442e62febec2004f79e041b" } ], "title": "drivers/perf: hisi_pcie: Fix out-of-bound access when valid event group", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2024-06-24T18:24:22.058209Z", "id": "CVE-2024-38569", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-24T18:24:28.077Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T04:12:26.114Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/3d1face00ebb7996842aee4214d7d0fb0c77b1e9", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/8e9aab2492178f25372f1820bfd9289fbd74efd0", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/567d34626c22b36579ec0abfdf5eda2949044220", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/ff48247144d13a3a0817127703724256008efa78", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/77fce82678ea5fd51442e62febec2004f79e041b", "tags": [ "x_transferred" ] } ] } ] } }
