No network or remote peer data is involved.\nAC:L - The overflow is fully deterministic — no race, no memory-layout luck: on a controller configured with 14 total ports the write to pconfig[14] happens on every probe, and allocating port 14 for a stream deterministically reads the out-of-bounds entry.\nPR:L - On an affected platform the out-of-bounds pconfig[14] access is triggerable at runtime by any local user able to open the SoundWire PCM device (audio group, or any Android app with audio access) through the normal stream-allocation path, with no capability required.\nUI:N - No victim action is needed — the probe-time write occurs automatically at boot, and the runtime path is driven entirely by the attacker's own PCM open/hw_params sequence.\nS:U - Both the flaw and its consequences are kernel memory corruption within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The out-of-bounds access straddles ctrl->sruntime[0], so the read path exposes bytes of a kernel heap pointer (defeating KASLR) and the corresponding write is memory corruption that can be leveraged for further disclosure.\nI:H - This is an out-of-bounds write that overwrites the low 32 bits of an adjacent kernel pointer field with device-tree-derived values, corrupting kernel state outside the intended object.\nA:H - Corrupting the sdw_stream_runtime pointer stored in ctrl->sruntime[0] can lead to a wild dereference and kernel oops when the stream is subsequently used, taking down the system." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/soundwire/qcom.c" ], "versions": [ { "version": "9916c02ccd74e672b62dd1a9017ac2f237ebf512", "lessThan": "20f7c4d51c94abb1a1a7c21900db4fb5afe5c8ff", "status": "affected", "versionType": "git" }, { "version": "9916c02ccd74e672b62dd1a9017ac2f237ebf512", "lessThan": "801daff0078087b5df9145c9f5e643c28129734b", "status": "affected", "versionType": "git" }, { "version": "9916c02ccd74e672b62dd1a9017ac2f237ebf512", "lessThan": "32eb67d7360d48c15883e0d21b29c0aab9da022e", "status": "affected", "versionType": "git" }, { "version": "9916c02ccd74e672b62dd1a9017ac2f237ebf512", "lessThan": "490937d479abe5f6584e69b96df066bc87be92e9", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/soundwire/qcom.c" ], "versions": [ { "version": "5.13", "status": "affected" }, { "version": "0", "lessThan": "5.13", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.121", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.40", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.4.5", "lessThanOrEqual": "6.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.5", "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": "5.13", "versionEndExcluding": "5.15.121" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "6.1.40" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "6.4.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "6.5" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/20f7c4d51c94abb1a1a7c21900db4fb5afe5c8ff" }, { "url": "https://git.kernel.org/stable/c/801daff0078087b5df9145c9f5e643c28129734b" }, { "url": "https://git.kernel.org/stable/c/32eb67d7360d48c15883e0d21b29c0aab9da022e" }, { "url": "https://git.kernel.org/stable/c/490937d479abe5f6584e69b96df066bc87be92e9" } ], "title": "soundwire: qcom: fix storing port config out-of-bounds", "x_generator": { "engine": "bippy-1.2.0" } } } }
