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

Description An issue exists in the rocket probe function where improper unwinding occurs during an error path. When the rocket core init() function fails, such as in cases involving EPROBE DEFER, the system fails to correctly decrement the incremented counter and does not remove the rocket DRM device using rocket device fini() if it is the first core that failed to probe. This failure to properly unwind leads to out-of-bounds accesses.

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