Description OSIDB Bzimport 2025-08-19 18:01:26 UTC 
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.
