CVE-2026-43476 Details
Description
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.
A vulnerability exists in the Linux kernel's IIO chemical SPS30 I2C driver, specifically in the measurement reading function. The issue arises because the buffer size calculation incorrectly uses the size of 'num', which evaluates to 8 bytes on a 64-bit system, instead of the correct element size of 4 bytes for a __be32 type. This miscalculation can lead to buffer handling errors. The vulnerability affects the stable versions of the Linux kernel.
The vulnerability has been addressed in the Linux kernel. Users can upgrade to the latest stable version to apply the fix.
