this requires local access to SOF-equipped audio hardware, not remote network delivery.\nAC:L - On affected 32-bit builds, firmware-supplied num_elems deterministically wraps expected_size so the hdr.size check passes; a local attacker can repeatedly drive DSP control notifications through ALSA without uncontrollable races or victim-specific state.\nPR:L - Only an unprivileged local user able to open ALSA control devices on SOF IPC3 hardware (typical audio-group access on laptops, Chromebooks, and 32-bit embedded tablets) is needed to exercise DSP control paths that deliver the malformed IPC payloads.\nUI:N - No separate victim interaction is required; the attacker triggers SOF control-update handling through their own ALSA audio/control activity and the kernel processes the malformed IPC notification automatically.\nS:U - Heap corruption and control-cache overread/overwrite remain within the host kernel audio driver on the same machine and do not cross VM, container, or IOMMU boundaries into another security authority.\nC:H - Bypassed size validation lets snd_sof_update_control() read chanv/binary data past the kmalloc IPC buffer via loops or memcpy, yielding out-of-bounds kernel heap reads that can disclose adjacent memory contents.\nI:H - Crafted num_elems drives out-of-bounds copying from the IPC message into control caches, corrupting kernel heap objects and enabling attacker-influenced writes exploitable for further privilege escalation.\nA:H - Out-of-bounds accesses during IRQ-threaded IPC3 control-update handling can cause KASAN faults, unhandled page faults, kernel oops, or panic under realistic SOF audio workloads on 32-bit systems."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["sound/soc/sof/ipc3-control.c"], "versions": [{"version": "10f461d79c2d1afb22344986cc1b4631169cf25e", "lessThan": "6856b3c23b0995eefad5a6142b4365ef70e1fe4a", "status": "affected", "versionType": "git"}, {"version": "10f461d79c2d1afb22344986cc1b4631169cf25e", "lessThan": "89a2309a9eec80d4c19e3aed62c4f923594d1911", "status": "affected", "versionType": "git"}, {"version": "10f461d79c2d1afb22344986cc1b4631169cf25e", "lessThan": "ffd79e77f2fbacd7a5d40ad1d4c7f3f089a8f2f3", "status": "affected", "versionType": "git"}, {"version": "10f461d79c2d1afb22344986cc1b4631169cf25e", "lessThan": "711d912b18763af62a63aa8f2419a774eb63bba4", "status": "affected", "versionType": "git"}, {"version": "10f461d79c2d1afb22344986cc1b4631169cf25e", "lessThan": "312c7d2ebe696da3f885eee77d52297664e57c53", "status": "affected", "versionType": "git"}, {"version": "10f461d79c2d1afb22344986cc1b4631169cf25e", "lessThan": "8791977d7289f6e9d2b014f60a5455f053a7bc04", "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/sof/ipc3-control.c"], "versions": [{"version": "5.18", "status": "affected"}, {"version": "0", "lessThan": "5.18", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.178", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.145", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.97", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.40", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.5", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2", "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": "6.1.178"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.6.145"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.12.97"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.18.40"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "7.1.5"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "7.2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/6856b3c23b0995eefad5a6142b4365ef70e1fe4a"}, {"url": "https://git.kernel.org/stable/c/89a2309a9eec80d4c19e3aed62c4f923594d1911"}, {"url": "https://git.kernel.org/stable/c/ffd79e77f2fbacd7a5d40ad1d4c7f3f089a8f2f3"}, {"url": "https://git.kernel.org/stable/c/711d912b18763af62a63aa8f2419a774eb63bba4"}, {"url": "https://git.kernel.org/stable/c/312c7d2ebe696da3f885eee77d52297664e57c53"}, {"url": "https://git.kernel.org/stable/c/8791977d7289f6e9d2b014f60a5455f053a7bc04"}], "title": "ASoC: SOF: ipc3-control: Use overflow checks in control_update size calc", "x_generator": {"engine": "bippy-1.2.0"}}}}
