There is no remote or adjacent-network path into the sc7280 machine driver.\nAC:L - On an affected sc7280 board (audioreach/ADSP device tree, where cpu_dai->id is a q6afe port id such as RX_CODEC_DMA_RX_0=113), the index is unconditionally out of the 34-entry arrays, so a single open()/close() or hw_params() deterministically triggers the OOB read, write and kfree() — no race, no timing, no memory-layout luck required to trigger.\nPR:L - The attacker needs only an unprivileged local account with access to the PCM device node — membership in the \"audio\" group on Chromebook/embedded systems, or an ordinary audio-capable app on Android. No capability, root, or namespace privilege is checked anywhere along the soc_pcm_open/soc_pcm_hw_params path.\nUI:N - The attacker opens and configures the PCM device directly; no victim must plug in hardware, mount anything, or play audio. The vulnerable callbacks run purely as a result of the attacker's own syscalls.\nS:U - The corruption is confined to kernel heap memory within the same kernel security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - sc7280_snd_shutdown() reads a pointer from out of bounds (data->sruntime[113/120]) and hands it to kfree(), and the OOB pointer write can clobber an adjacent heap object; such heap corruption plus an attacker-groomable free is readily leveraged into arbitrary kernel memory disclosure.\nI:H - hw_params() writes a kernel heap pointer, and prepare() writes a byte, hundreds of bytes past the end of the 34-entry arrays inside the devm_kzalloc'd sc7280_snd_data object, and shutdown() frees an out-of-bounds-read pointer — an out-of-bounds write plus an invalid free, both classic primitives for control-flow hijacking.\nA:H - Corrupting an adjacent slab object and calling kfree() on a pointer read from out of bounds reliably produces slab corruption, BUG_ON/KASAN reports, or a kernel panic, and the sequence can be repeated at will by an unprivileged local user." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "sound/soc/qcom/lpass.h" ], "versions": [ { "version": "77d0ffef793da818741127f4905a3e3d45d05ac7", "lessThan": "d78888853eb53f47ae16cf3aa5d0444d0331b9f8", "status": "affected", "versionType": "git" }, { "version": "77d0ffef793da818741127f4905a3e3d45d05ac7", "lessThan": "a12c14577882b1f2b4cff0f86265682f16e97b0c", "status": "affected", "versionType": "git" }, { "version": "77d0ffef793da818741127f4905a3e3d45d05ac7", "lessThan": "c0ce01e0ff8a0d61a7b089ab309cdc12bc527c39", "status": "affected", "versionType": "git" }, { "version": "77d0ffef793da818741127f4905a3e3d45d05ac7", "lessThan": "b807b7c81a6d066757a94af7b8fa5b6a37e4d0b3", "status": "affected", "versionType": "git" }, { "version": "77d0ffef793da818741127f4905a3e3d45d05ac7", "lessThan": "a31a4934b31faea76e735bab17e63d02fcd8e029", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "sound/soc/qcom/lpass.h" ], "versions": [ { "version": "5.18", "status": "affected" }, { "version": "0", "lessThan": "5.18", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.136", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.88", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.25", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.14.4", "lessThanOrEqual": "6.14.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.15", "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": "5.18", "versionEndExcluding": "6.1.136" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.6.88" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.12.25" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.14.4" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.15" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/d78888853eb53f47ae16cf3aa5d0444d0331b9f8" }, { "url": "https://git.kernel.org/stable/c/a12c14577882b1f2b4cff0f86265682f16e97b0c" }, { "url": "https://git.kernel.org/stable/c/c0ce01e0ff8a0d61a7b089ab309cdc12bc527c39" }, { "url": "https://git.kernel.org/stable/c/b807b7c81a6d066757a94af7b8fa5b6a37e4d0b3" }, { "url": "https://git.kernel.org/stable/c/a31a4934b31faea76e735bab17e63d02fcd8e029" } ], "title": "ASoC: qcom: Fix sc7280 lpass potential buffer overflow", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T19:57:56.701Z" } } ] } }
