Alignment Vulnerability in Linux Kernel's hwmon for ARMv5 and SPARC

CVE-2026-80695

What is CVE-2026-80695?

A vulnerability has been identified in the Linux kernel's hwmon subsystem that affects the alignment of 16-bit temperature and humidity data retrieval. The issue originates from the method used to access the data, which can lead to unaligned memory access, triggering alignment faults on strict-alignment architectures like ARMv5 and SPARC. This misalignment can cause a kernel panic, compromising system stability. The vulnerability has been addressed by updating the data access methods to ensure proper alignment, thereby preventing potential system crashes.
