Linux Kernel Memory Leak Vulnerability in Tracing Component

A memory leak vulnerability has been identified in the Linux kernel's tracing component. The issue arises in the functions test_gen_synth_cmd() and test_empty_synth_event(), where allocated memory is not properly freed under certain conditions. This oversight can lead to a gradual increase in memory usage, potentially causing performance degradation. The vulnerability has been addressed by modifying these functions to ensure that allocated memory is correctly released, preventing the memory leak.

Impact

Exploitation of this vulnerability leads to a memory leak, where allocated memory is not properly freed, causing increased memory usage over time.
