CVE-2026-43210

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