Title
iio: chemical: sps30_i2c: fix buffer size in sps30_i2c_read_meas()
Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: chemical: sps30_i2c: fix buffer size in sps30_i2c_read_meas()
sizeof(num) evaluates to sizeof(size_t) (8 bytes on 64-bit) instead
of the intended __be32 element size (4 bytes). Use sizeof(*meas) to
correctly match the buffer element type.

{
"lang": "en",
"value": "AV:L - An attacker reaches the vulnerable path by locally reading world-readable IIO sysfs channel attributes for the SPS30 I2C device, which invoke the driver read path. The bug is not exposed through a network protocol or adjacent wireless interface.\nAC:L - Triggering requires only a normal measurement read once an affected SPS30 I2C device is present; there is no race and the attacker controls repeated attempts. The 64-bit size_t condition is a common affected platform property, not an exploitation hurdle.\nPR:L - The raw IIO channel attributes are created read-only with mode 0444, so any basic local unprivileged user can trigger the vulnerable read. No CAP_SYS_ADMIN, CAP_NET_ADMIN, root-only ioctl, or user-namespace capability path is required.\nUI:N - No victim action is required after the attacker has local access. The attacker can directly read the exposed sysfs attribute.\nS:U - The memory corruption occurs in kernel driver context and affects the same kernel security authority. This is a standard local kernel compromise scenario, not a VM, IOMMU, or sandbox boundary crossing that changes scope.\nC:H - The old sizeof(num) calculation causes decoded I2C measurement data to be copied past the caller\u0027s 32-bit measurement buffer on the kernel stack. As an out-of-bounds stack write, this memory corruption is defensibly treated as capable of enabling kernel information disclosure.\nI:H - The bug is an out-of-bounds kernel stack write of up to 16 bytes on the PM10/read-buffer path, and repeated local triggering is possible. Kernel OOB writes are treated as high integrity impact because they can plausibly corrupt control data or other sensitive stack state.\nA:H - The stack corruption can crash or oops the kernel, especially with stack protector or corrupted adjacent state. Repeated unprivileged reads can therefore cause high availability impact."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
