no network or physical attack path exists.\nAC:L - Writable production controls commonly use allocator-boundary maxima such as 1024 bytes, and a malformed nested TLV deterministically produces an attacker-controlled heap overflow without a race or firmware interaction.\nPR:L - The path requires ordinary unprivileged access to the ALSA control device, commonly granted to the active desktop user or audio group, and performs no capability or namespace privilege check.\nUI:N - After obtaining local ALSA control-device access, the attacker can issue the malicious TLV ioctl directly without any victim action.\nS:U - The vulnerable ALSA/SOF driver and the affected kernel resources share the same security authority; ordinary kernel privilege escalation does not change CVSS scope.\nC:H - The size mismatch permits an adjacent heap out-of-bounds read through the TLV get path, while heap corruption can also be leveraged to disclose sensitive kernel memory.\nI:H - The TLV write path copies attacker-controlled bytes past the undersized allocation, providing a controlled adjacent heap overwrite that can plausibly corrupt pointers or enable control-flow hijacking.\nA:H - The heap overflow can corrupt adjacent kernel objects and cause an oops or panic, and it can be triggered repeatedly through the control ioctl." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "sound/soc/sof/ipc4-topology.c" ], "versions": [ { "version": "a382082ff74b036944cbc5b6ad29b65f633acd3a", "lessThan": "59fe643f21b9d59bcbedb0dfbf988ee455c23736", "status": "affected", "versionType": "git" }, { "version": "a382082ff74b036944cbc5b6ad29b65f633acd3a", "lessThan": "491956b45b5f4933632ea6d8a8bdfdf045ab81e1", "status": "affected", "versionType": "git" }, { "version": "a382082ff74b036944cbc5b6ad29b65f633acd3a", "lessThan": "a704a1a4394b5877b9adc31b2c3165ad0b541896", "status": "affected", "versionType": "git" }, { "version": "a382082ff74b036944cbc5b6ad29b65f633acd3a", "lessThan": "1237cd9ff198cb882402572f29569e5247190974", "status": "affected", "versionType": "git" }, { "version": "a382082ff74b036944cbc5b6ad29b65f633acd3a", "lessThan": "a653820700b81c9e6f05ac23b7969ecec1a18e85", "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/ipc4-topology.c" ], "versions": [ { "version": "6.4", "status": "affected" }, { "version": "0", "lessThan": "6.4", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.128", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.75", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.16", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.19.6", "lessThanOrEqual": "6.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.0", "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": "6.6.128" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.12.75" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.18.16" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.19.6" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "7.0" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/59fe643f21b9d59bcbedb0dfbf988ee455c23736" }, { "url": "https://git.kernel.org/stable/c/491956b45b5f4933632ea6d8a8bdfdf045ab81e1" }, { "url": "https://git.kernel.org/stable/c/a704a1a4394b5877b9adc31b2c3165ad0b541896" }, { "url": "https://git.kernel.org/stable/c/1237cd9ff198cb882402572f29569e5247190974" }, { "url": "https://git.kernel.org/stable/c/a653820700b81c9e6f05ac23b7969ecec1a18e85" } ], "title": "ASoC: SOF: ipc4-topology: Correct the allocation size for bytes controls", "x_generator": { "engine": "bippy-1.2.0" } } } }
