CVE-2026-43210 tracing: ring-buffer: Fix to check event length before using

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 rbreaddatabuffer. Since this function is used for validating possibly broken ring buffers, the lengt...

CVE-2026-43210

The CVE-2026-43210 entry concerns the Linux kernel tracing ring-buffer subsystem. The root cause is inadequate validation of event length in rb_read_data_buffer(), which can cause an invalid memory access if an event’s length is corrupted, potentially at boot time. The published fix is to check t...
