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...

In the Linux kernel, the following vulnerability has been resolved: tracing/fprobe: Fix NULL pointer dereference in fprobefgraphentry fprobefgraphentry sizes a shadow-stack reservation in one walk of the per-ip fprobe list and fills it in a second walk, both under rcureadlock only. A fprobe...

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...

CVE-2026-72012

CVE-2026-72012 affects the Linux kernel’s tracing/osnoise path. The underlying issue is that, during unregistering, a synchronize_rcu() call was missing, risking that RCU readers traversing the instance list may still hold references when the tracer is released. The description states that the vu...
