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...
