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"}}]}}
