CVE-2025-40132

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw within the ASoC (Audio Subsystem on Chip) Intel sof sdw component. Specifically, the create sdw dailink() function does not adequately verify that the add sidecar callback is not NULL before attempting to call it. This can lead to a jump to a NULL address if a codec lacking this callback is present on the same link, potentially causing a system crash or other undefined behavior. The issue arises from an assumption that all codecs on a link will have an add sidecar callback when include sidecar is true.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
