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

Description A flaw exists in the Linux kernel's ASoC (Advanced Linux Sound Architecture) pxa module. Specifically, a null-pointer dereference can occur within the filter() function. This happens when kasprintf() fails to allocate memory and returns a NULL pointer, which is then used in a subsequent strcmp() comparison without proper validation.

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