CVE-2025-38573

Estado: ModificadaMedia (5.5)—

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.
