CVE-2026-80695

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

hwmon: (sht3x) Fix unaligned accesses

Sashiko reports:

In sht3x_update_client(), the 16-bit temperature and humidity values are

extracted from a stack-allocated byte array using be16_to_cpup(). The

pointers passed to this function are calculated as buf and buf + 3. Since

the difference between the two pointers is an odd number of bytes, at

least one of them is guaranteed to be at an unaligned offset.

This will trigger an alignment fault on strict-alignment architectures

such as ARMv5 or SPARC, resulting in a kernel panic.

Fix the problem by using get_unaligned_be16() instead of be16_to_cpup(),

and put_unaligned_be16() instead of cpu_to_be16().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
