7.1 · HIGHOverview
CVE-2022-49799 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 1, 2025 and has a CVSS 3.1 base score of 7.1 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix wild-memory-access in register_synth_event()
In register_synth_event(), if set_synth_event_print_fmt() failed, then
both trace_remove_event_call() and unregister_trace_event() will be
called, which means the trace_event_call will call
__unregister_trace_event() twice. As the result, the second unregister
will causes the wild-memory-access.
register_synth_event
set_synth_event_print_fmt failed
trace_remove_event_call
event_remove
if call->event.funcs then
__unregister_trace_event (first call)
unregister_trace_event
__unregister_trace_event (second call)
Fix the bug by avoiding to call the second __unregister_trace_event() by
checking if the first one is called.
