no attacker-uncontrollable memory layout or victim state is required beyond that.\nPR:L - The ingredient the attacker must supply — sustained memory pressure that makes the GFP_KERNEL allocation fail — needs only an unprivileged local account; the probe event itself is a system action rather than a privilege the attacker must hold.\nUI:N - No victim action is needed — the faulty error path executes inside the kernel's own device probe, with no user having to open a file, mount anything, or interact.\nS:U - The out-of-bounds read, invalid free, and leaked allocations all stay within the kernel's own slab allocator and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - When the first allocation fails the loop indexes the array at -1 and further negative offsets, an unbounded out-of-bounds read of kernel heap memory below the allocation; combined with the resulting potential use-after-free this is treatable as an arbitrary kernel-memory read primitive.\nI:H - Passing an out-of-bounds-read word to kfree() is an arbitrary/wild free — if that word is a live heap pointer a still-referenced object is released, giving a classic use-after-free heap-corruption primitive usable for control-flow hijacking.\nA:H - Freeing a garbage pointer near-certainly triggers a slab BUG/general-protection-fault kernel panic, and even the benign variant of the bug permanently leaks kernel allocations on every failed probe." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/iio/industrialio-gts-helper.c" ], "versions": [ { "version": "38416c28e16890b52fdd5eb73479299ec3f062f3", "lessThan": "62c11896683129790b8f5ab6eb7e695818b0b723", "status": "affected", "versionType": "git" }, { "version": "38416c28e16890b52fdd5eb73479299ec3f062f3", "lessThan": "b304362ce836968b803e5d4c5f84dcb51a7bf0f2", "status": "affected", "versionType": "git" }, { "version": "38416c28e16890b52fdd5eb73479299ec3f062f3", "lessThan": "369f05688911b05216cfcd6ca74473bec87948d7", "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/iio/industrialio-gts-helper.c" ], "versions": [ { "version": "6.4", "status": "affected" }, { "version": "0", "lessThan": "6.4", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.60", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.7", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "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": "6.4", "versionEndExcluding": "6.6.60" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.11.7" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/62c11896683129790b8f5ab6eb7e695818b0b723" }, { "url": "https://git.kernel.org/stable/c/b304362ce836968b803e5d4c5f84dcb51a7bf0f2" }, { "url": "https://git.kernel.org/stable/c/369f05688911b05216cfcd6ca74473bec87948d7" } ], "title": "iio: gts-helper: Fix memory leaks for the error path of iio_gts_build_avail_scale_table()", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 5.5, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2024-53076", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2025-10-01T20:12:14.041082Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-401", "description": "CWE-401 Missing Release of Memory after Effective Lifetime" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T20:17:15.740Z" } } ] } }
