CVE-2026-43210 at MITRE

Description

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.
