CVE-2026-74471

In the Linux kernel tracing subsystem, CVE-2026-74471 is caused by trace_module_add_events() ignoring the return value of __register_event(): if registration fails, a trace_event_call may still be linked via __add_event_to_tracers(), creating a stale pointer that can lead to a use-after-free when...

CVE-2026-74391

In CVE-2026-74391, the Linux kernel tracing subsystem is affected by a buffer-overflow risk in synthetic-field string construction. The vulnerability arises because synthetic field helpers append strings with strcat() to fixed MAX_FILTER_STR_VAL buffers, allowing long key lists, field names, or s...

CVE-2026-72385

CVE-2026-72385 concerns the Linux kernel tracing/fprobe component. The issue is a NULL pointer dereference in fprobe_fgraph_entry() caused by mis-synchronization between two walks that size and fill a shadow-stack reservation under rcu_read_lock(). If a fprobe on an already-live ip becomes visibl...
