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

Description The Linux kernel contains a flaw in the tracing subsystem related to handling synthetic events. Specifically, the synthetic event field "char file[]" can read a string value without validating the memory address, potentially leading to a crash when accessing user space addresses via functions like strlen() and strscpy(). The issue occurs when executing commands that involve creating and enabling synthetic events with file paths.

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