VectorAV: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 Linux kernel contains a flaw within the interconnect component related to debugfs handling. Specifically, the src node and dst node variables were not initialized before being used with the debugfs create str() API. This API requires either a NULL pointer or a pointer to valid memory allocated with kmalloc(). Failure to initialize these pointers could lead to issues during reads and writes. The issue is addressed by initializing src node and dst node to empty strings before creating the debugfs entries, ensuring safe operations.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
