CVE-2026-46326
Description
A flaw was found in the Linux kernel, specifically within the iio: pressure: mprls0025pa driver. This vulnerability is due to improper initialization of the spi_transfer structure, which is not consistently zeroed out before use. This could allow an attacker to potentially read sensitive information from uninitialized memory or cause a denial of service due to unpredictable system behavior.
Understanding the Weakness (CWE)

Availability
Technical Impact: DoS: Crash, Exit, or Restart
The uninitialized resource may contain values that cause program flow to change in ways that the programmer did not intend.
