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

Description The issue is related to a double free error in the error handling of the gp aux bus probe() function in the Linux kernel. When auxiliary device add() returns an error and then calls auxiliary device uninit(), the callback function gp auxiliary device release() calls ida free() and kfree(aux device wrapper) to free memory. However, these functions should not be called again in the error handling path. This can potentially allow an attacker to impact the availability of protected information.

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