CVE-2026-97923

The Linux kernel contains a memory leak vulnerability within the tracing subsystem. Specifically, the create_var_ref() function allocates a VAR_REF hist_field and calls init_var_ref() to populate it. If init_var_ref() fails, the allocated field is leaked because it is not added to the trigger's v...

CVE-2026-97924

The Linux kernel contains a vulnerability in the tracing/user_events component. The destroy_user_event() function incorrectly destroys an event's fields before attempting to remove the trace event call. If the removal fails (e.g., returning -EBUSY because the event is still enabled), the event re...

CVE-2026-97922 tracing: Free histogram var refs regardless of how often they are referenced

In the Linux kernel, the following vulnerability has been resolved: tracing: Free histogram var refs regardless of how often they are referenced Using the same variable three or more times in one hist trigger leaks the variable reference and its strings when the trigger is removed. commit...

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...

CVE-2026-97922

The Linux kernel contains a memory leak vulnerability in the tracing subsystem. Specifically, using the same variable three or more times in a single hist trigger causes the variable reference and its associated strings to leak when the trigger is removed. The root cause is that while repeated re...
