- Summary
- tracing: Hold trace_types_lock when resetting last boot data from readers
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
tracing: Hold trace_types_lock when resetting last boot data from readers
update_last_data_if_empty() is called from tracing_open() with O_TRUNC, tracing_read_pipe() and tracing_buffers_read() without trace_types_lock. Two readers can both pass the LAST_BOOT test and free module_delta twice, and a module notifier can update module_delta while it is being freed.
Take trace_types_lock in those paths and keep the callers that already hold it on an unlocked variant.
