there is no network- or peer-supplied data path into `soc_tplg_dapm_graph_elems_load()`.\nAC:L - The dangling pointers are created unconditionally on every affected platform the moment `release_firmware()` runs after topology load — no race, no timing window, and no memory-layout precondition outside attacker influence, since the attacker can groom the freed vmalloc/kmalloc region with ordinary allocations before the stale pointers are used.\nPR:L - The freed-memory references are established automatically at boot with zero privilege, and an ordinary unprivileged local user with default `/dev/snd` access (granted to the console user by logind ACLs, or the `audio` group) can drive DAPM path re-evaluation and spray the freed pages; no root or capability is needed to reach the affected state.\nUI:N - Topology parsing and the subsequent `release_firmware()` happen automatically during sound-card initialization on affected Intel AVS/SOF and Qualcomm qdsp6 systems, with no action required from any victim user.\nS:U - The stale pointers, the freed firmware buffer, and any resulting corruption are all confined to the kernel of the same system; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Reads through the dangling `route->source/sink/control` pointers pull whatever kernel data has been reallocated into the freed firmware pages, and those bytes are used as widget/control names and printed via `dev_dbg`/`dev_err` in `sof_route_load()` and `snd_soc_dapm_add_route()`, disclosing arbitrary reallocated kernel memory.\nI:H - The stale pointers are also written through — Intel AVS did `strscpy((char *)route->source, buf, len)` on them (fixed in companion commit fd660b1bd015) — giving a write into memory that now belongs to some other kernel allocation, which is a classic use-after-free write primitive usable for control-flow hijacking.\nA:H - Dereferencing pointers into a released vmalloc'd firmware buffer produces a use-after-free that readily oopses or panics the kernel, and the follow-up \"ASoC: topology: Fix route memory corruption\" commit confirms real-world memory corruption in this exact code." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "sound/soc/soc-topology.c" ], "versions": [ { "version": "7df04ea7a31eaa75bdad2905f07cc097b15558ee", "lessThan": "b188d7f3dfab10e332e3c1066e18857964a520d2", "status": "affected", "versionType": "git" }, { "version": "7df04ea7a31eaa75bdad2905f07cc097b15558ee", "lessThan": "ab5a6208b4d6872b1c6ecea1867940fc668cc76d", "status": "affected", "versionType": "git" }, { "version": "7df04ea7a31eaa75bdad2905f07cc097b15558ee", "lessThan": "ccae5c6a1fab9494c86b7856faf05e296c617702", "status": "affected", "versionType": "git" }, { "version": "7df04ea7a31eaa75bdad2905f07cc097b15558ee", "lessThan": "97ab304ecd95c0b1703ff8c8c3956dc6e2afe8e1", "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/soc-topology.c" ], "versions": [ { "version": "5.1", "status": "affected" }, { "version": "0", "lessThan": "5.1", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.101", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.42", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9.11", "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": "5.1", "versionEndExcluding": "6.1.101" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.1", "versionEndExcluding": "6.6.42" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.1", "versionEndExcluding": "6.9.11" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.1", "versionEndExcluding": "6.10" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/b188d7f3dfab10e332e3c1066e18857964a520d2" }, { "url": "https://git.kernel.org/stable/c/ab5a6208b4d6872b1c6ecea1867940fc668cc76d" }, { "url": "https://git.kernel.org/stable/c/ccae5c6a1fab9494c86b7856faf05e296c617702" }, { "url": "https://git.kernel.org/stable/c/97ab304ecd95c0b1703ff8c8c3956dc6e2afe8e1" } ], "title": "ASoC: topology: Fix references to freed memory", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/b188d7f3dfab10e332e3c1066e18857964a520d2", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/ab5a6208b4d6872b1c6ecea1867940fc668cc76d", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/ccae5c6a1fab9494c86b7856faf05e296c617702", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/97ab304ecd95c0b1703ff8c8c3956dc6e2afe8e1", "tags": [ "x_transferred" ] }, { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:00:19.311Z" } }, { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-41069", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-09-10T16:21:43.300028Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-11T17:34:01.067Z" } } ] } }
