Description

In the Linux kernel, the following vulnerability has been resolved: spi: cs42l43: Property entry should be a null-terminated array The software node does not specify a count of property entries, so the array must be null-terminated. When unterminated, this can lead to a fault in the downstream cs35l56 amplifier driver, because the node parse walks off the end of the array into unknown memory.

Affected products

• Linux kernel: from 6.11 before 6.12.42; from 6.13 before 6.15.10; from 6.16 before 6.16.1 — fixed in 6.12.42, 6.15.10, 6.16.1

How to fix

Upgrade to a fixed version: Linux kernel 6.12.42, 6.15.10, 6.16.1. Check the vendor advisory for mitigations.
