no network protocol, packet, or remote peer data reaches the frequency-table walk.\nAC:L - The over-read is fully deterministic — any rate request exceeding the table's largest entry runs the loop off the array end with no race, timing window, or memory-layout precondition involved.\nPR:L - No real-root capability check guards the rate-setting path; the affected RCGs are re-programmed by consumer drivers on paths an unprivileged local user can provoke (device-node open triggering runtime-PM resume on the USB/PCIe controllers, QPIC/NAND I/O), so basic local user privileges are sufficient rather than init-namespace root.\nUI:N - The out-of-bounds walk occurs entirely within kernel clock-rate handling during normal driver operation; no victim must open a file, mount a filesystem, or take any other action.\nS:U - The over-read and its consequences stay within the kernel's own security authority — there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The loop performs an unbounded out-of-bounds read of kernel `.rodata` past the array, and the read `freq` field is propagated back as the clock rate visible through the clk debugfs/round-rate interfaces, so out-of-bounds kernel memory — potentially including relocated pointers usable to defeat KASLR — is disclosed; the read is not bounded to a few bytes.\nI:L - There is no out-of-bounds write and no kernel memory corruption — `src` is validated by `qcom_find_src_index()` and `m`/`n`/`pre_div` are masked before reaching hardware — but out-of-bounds-derived values are still programmed into the SoC's RCG clock-control registers, mis-configuring the PCIe/USB aux, QPIC NAND I/O-macro, or UBI32 core clocks and thereby corrupting data clocked through the NAND interface.\nA:H - With `IPQ_GCC_5018` built as a module the tables sit in vmalloc'd module `.rodata`, so the runaway walk can hit an unmapped guard region and oops the kernel, and programming garbage divider/source values into the PCIe, USB, QPIC, or UBI32 clock RCGs can hang the affected peripheral or the SoC outright." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/clk/qcom/gcc-ipq5018.c" ], "versions": [ { "version": "e3fdbef1bab8e372981c8cc4d8febbaa76c490b0", "lessThan": "b0cf3d200e8a72b6d28e6e088c062b4a98cb5eaf", "status": "affected", "versionType": "git" }, { "version": "e3fdbef1bab8e372981c8cc4d8febbaa76c490b0", "lessThan": "c8f4bef0667947b826848db1c45a645f751357c1", "status": "affected", "versionType": "git" }, { "version": "e3fdbef1bab8e372981c8cc4d8febbaa76c490b0", "lessThan": "50c3acd460551cdf9d8ac6fe0c04f2de0e8e0872", "status": "affected", "versionType": "git" }, { "version": "e3fdbef1bab8e372981c8cc4d8febbaa76c490b0", "lessThan": "90ad946fff70f312b8d23226afc38c13ddd88c4b", "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/clk/qcom/gcc-ipq5018.c" ], "versions": [ { "version": "6.6", "status": "affected" }, { "version": "0", "lessThan": "6.6", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.24", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7.12", "lessThanOrEqual": "6.7.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.3", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9", "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": "6.6.24" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.7.12" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.8.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.9" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/b0cf3d200e8a72b6d28e6e088c062b4a98cb5eaf" }, { "url": "https://git.kernel.org/stable/c/c8f4bef0667947b826848db1c45a645f751357c1" }, { "url": "https://git.kernel.org/stable/c/50c3acd460551cdf9d8ac6fe0c04f2de0e8e0872" }, { "url": "https://git.kernel.org/stable/c/90ad946fff70f312b8d23226afc38c13ddd88c4b" } ], "title": "clk: qcom: gcc-ipq5018: fix terminating of frequency table arrays", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-26971", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-05-01T13:37:17.172214Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-07-05T17:22:44.592Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T00:21:05.667Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/b0cf3d200e8a72b6d28e6e088c062b4a98cb5eaf", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/c8f4bef0667947b826848db1c45a645f751357c1", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/50c3acd460551cdf9d8ac6fe0c04f2de0e8e0872", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/90ad946fff70f312b8d23226afc38c13ddd88c4b", "tags": [ "x_transferred" ] } ] } ] } }
