CVE-2026-97921

The Linux kernel contains a memory leak in the tracing subsystem. When creating a histogram trigger with a value or variable carrying an invalid modifier, the kernel identifies the error but fails to free the allocated field because it is skipped during the store operation. This results in unrefe...
