CVE-2026-43476

CVE-2026-43476 affects the Linux kernel’s IIO sensor driver for SPS30 (iio: chemical: sps30_i2c). The root cause is a faulty buffer size calculation in sps30_i2c_read_meas() where sizeof(num) yields sizeof(size_t) (8 bytes on 64-bit) instead of the intended 4-byte __be32 element size; the fix use...

CVE-2026-43476 iio: chemical: sps30_i2c: fix buffer size in sps30_i2c_read_meas()

In the Linux kernel, the following vulnerability has been resolved: iio: chemical: sps30i2c: fix buffer size in sps30i2creadmeas sizeofnum evaluates to sizeofsizet 8 bytes on 64-bit instead of the intended be32 element size 4 bytes. Use sizeofmeas to correctly match the buffer element type...
