ParameterPositionPathDescriptionCWE
filepath/sys/kernel/tracing/dynamic_eventsVulnerability in synthetic event string reading allows unsafe user-space addresses to be processed when writing event description (char file[]) leading to potential crash/out-of-bounds access.CWE-125
filepath/sys/kernel/tracing/events/syscalls/sys_enter_openat/triggerTrigger endpoint for synthetic events uses a user-controlled string; unsafe handling can cause oops when processing the file path in open events.CWE-125
filepath/sys/kernel/tracing/events/synthetic/open/enableEnabling synthetic open event can expose unsafe string handling of the file argument; potential for crash due to improper memory checks.CWE-125
