Title
soundwire: qcom: fix storing port config out-of-bounds
Summary
In the Linux kernel, the following vulnerability has been resolved: soundwire: qcom: fix storing port config out-of-bounds The 'qcom_swrm_ctrl->pconfig' has size of QCOM_SDW_MAX_PORTS (14), however we index it starting from 1, not 0, to match real port numbers. This can lead to writing port config past 'pconfig' bounds and overwriting next member of 'qcom_swrm_ctrl' struct. Reported also by smatch: drivers/soundwire/qcom.c:1269 qcom_swrm_get_port_config() error: buffer overflow 'ctrl->pconfig' 14 <= 14
Severity

No network or remote peer data is involved.\nAC:L - The overflow is fully deterministic \u2014 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 \u2014 the probe-time write occurs automatically at boot, and the runtime path is driven entirely by the attacker\u0027s 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-\u003esruntime[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-\u003esruntime[0] can lead to a wild dereference and kernel oops when the stream is subsequently used, taking down the system."
