Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: tracing: ring-buffer: Fix to check event length before using Check the event length before adding it for accessing next index in rb_read_data_buffer(). Since this function is used for validating possibly broken ring buffers, the length of the event could be broken. In that case, the new event (e + len) can point a wrong address. To avoid invalid memory access at boot, check whether the length of each event is in the possible range before using it.
