Vulnerability from github – Published: 2026-05-13 18:30 – Updated: 2026-05-20 18:31

Details

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.

Severity ?

7.8 (High)
