A memory leak exists in the Linux kernel's tracing subsystem. When a tracing instance is removed, the error messages associated with that instance are not properly freed, leading to a memory leak. This issue occurs when using the
hist trigger with the sched/sched switch event and can be observed by creating and removing tracing instances within the /sys/kernel/tracing directory. The error log contains error messages that are not freed when the instance is removed.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
