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

Description A flaw exists in the Linux kernel related to the ALSA firewire-digi00x driver. Specifically, the code incorrectly handles errors during stream initialization, potentially leading to a use-after-free condition. The init stream() function was intended to return an error code upon failure, but instead freed memory and returned a success status. This can result in subsequent access to freed memory.

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