Base vector

AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

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

Description The issue is related to a possible null pointer dereference in the cs35l41 hda unbind() function. This function clears the hda component entry matching its index and then dereferences the codec pointer held in the first element of the hda component array. The problem arises when the device index is 0. To resolve this, the codec pointer stashed in the cs35l41 hda structure should be used instead, as it will still be valid.

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