CVE-2026-97935 tracing: Set the trace clock before registering the histogram trigger

In the Linux kernel, the following vulnerability has been resolved: tracing: Set the trace clock before registering the histogram trigger histregistertrigger puts the trigger on the global namedtriggers list in cmdops-init, and only then sets the trace clock: if data-cmdops-init ret =...

CVE-2026-97934 tracing: Fix memory corruption from a "STACKTRACE" histogram key

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix memory corruption from a "STACKTRACE" histogram key "cpu", "CPU", "stacktrace" and "STACKTRACE" are generic fields, defined with an offset and a size of zero so that the filter code can match them by name. parsefield...

CVE-2026-97934

The Linux kernel is vulnerable to memory corruption within the tracing subsystem. The issue arises because generic fields like "STACKTRACE" are mapped to placeholders instead of NULL by parse_field() . Consequently, create_hist_field() interprets data from the common_type field as an offset, lead...

CVE-2026-97935

The Linux kernel contains a slab-use-after-free vulnerability in the tracing subsystem. The issue occurs because hist_register_trigger() adds a histogram trigger to the global named_triggers list before validating the trace clock. If the clock string is unknown, tracing_set_clock() fails, causing...

CVE-2026-97933

The Linux kernel is vulnerable to a use-after-free race condition within the tracing subsystem. When a tracer option file is opened, the system uses a descriptor pointing to an element on the trace_array's topts array to increment the trace_array's reference counter. However, a race condition exi...

CVE-2026-97932

A vulnerability exists in the Linux kernel tracing subsystem where the enable_event trigger defers trace_event_put_ref() to the trigger free kthread. However, the trace_event_file can be freed prematurely when the instance is removed, leading to a use-after-free condition. The fix involves keepin...
