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

Description A memory leak was identified in the airspy probe within the Linux kernel. The commit ca9dc8d06ab6 moved a variable buf from the stack to the heap but only included deallocation in the error handling code, missing deallocation in the success path. This resulted in a memory leak when the success path was executed.

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