Linux kernel trace event trigger_data_free Heap Buffer Overflow DoS

The vulnerability of the triggerdatafree function in the kernel/trace/traceeventstrigger.c module, which supports kernel tracing in Linux operating systems, is related to the pointer dereferencing. Exploiting this vulnerability could allow an attacker to cause a service failure...

Linux kernel tracing DoS

The vulnerability of components related to Linux operating system kernel tracing is related to the insufficient use of the assert function. Exploiting this vulnerability can allow an attacker to cause a service failure...

Linux kernel trace event trigger function DoS

The vulnerability of the triggerkthreadfn function in the kernel/trace/traceeventstrigger.c module, which supports kernel tracing in Linux operating systems, relates to pointer manipulation. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

Linux Distros Unpatched Vulnerability : CVE-2026-74471

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tracing: Check return value of registerevent in tracemoduleaddevents tracemoduleaddevents ignores the return value of registerevent and unconditionally calls...

PT-2026-72573

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference exists in the fprobe fgraph entry function. The issue occurs because the function performs two separate walks of the per-ip fprobe list under rcu read lock to...

CVE-2026-68283 tracing: Fix use-after-free freeing trigger private data

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix use-after-free freeing trigger private data Commit 61d445af0a7c "tracing: Add bulk garbage collection of freeing eventtriggerdata" moved the kfree of eventtriggerdata to a kthread that runs...

CVE-2026-68176 tracing: Fix mmiotrace possible NULL dereferencing of hiter->dev

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix mmiotrace possible NULL dereferencing of hiter-dev If the mmiopipeopen fails to find a PCI device, the hiter-dev will be assigned to NULL. The mmiotrace read function dereferences the hiter-dev if hiter exists. Chang...

EUVD-2026-55276

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix resource leak on mmiotrace tracepipe close The mmiotrace tracer was added May 12th 2008. At that time, resources created in pipeopen could not be freed because there was not pipeclose function pointer of the tracer...

CVE-2026-68174

The vulnerability CVE-2026-68174 affects the Linux kernel tracing subsystem. In struct trace_event_call, the module pointer and the refcnt atomic share a union, so for dynamic events (kprobe, uprobe, fprobe, eprobe, wprobe) the refcnt may be non-zero and cause call->module to appear as a small...

Linux Distros Unpatched Vulnerability : CVE-2026-68146

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ftrace: Add global mutex to serialize traceparser access In ftrace, the traceparser structure is allocated and initialized when a trace file is opened, and is...

ROS-20260806-73-0032

The vulnerability of the tracepidwrite function in the kernel/trace/trace.c module, which supports Linux operating system tracing, is related to the repeated release of previously released memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity,...

CVE-2026-64451 tracing: Fix NULL pointer dereference in func_set_flag()

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix NULL pointer dereference in funcsetflag funcsetflag dereferences tr-currenttraceflags before verifying that the current tracer is actually the function tracer. When the active tracer has been switched away from...

CVE-2026-64299 tracing: Prevent out-of-bounds read in glob matching

In the Linux kernel, the following vulnerability has been resolved: tracing: Prevent out-of-bounds read in glob matching String event fields are not necessarily NUL-terminated, so the filter predicate functions filterpredstring, filterpredstrloc and filterpredstrrelloc pass the field length to th...

ftrace_modify_direct_caller Heap Buffer Overflow DoS

The vulnerability of the ftracemodifydirectcaller function in the kernel/trace/ftrace.c module, which supports kernel tracing in Linux operating systems, is related to the occurrence of mutual locking. Exploiting this vulnerability could allow an attacker to cause a service failure...

kernel/trace/rv/rv.c Heap Buffer Overflow DoS

The vulnerability of the enabledmonitorsstart function in the kernel/trace/rv/rv.c module, which is part of the Linux kernel’s tracing support, relates to the use of a wrong type of resource. Exploiting this vulnerability could allow an attacker to cause a service failure...

EUVD-2026-45858

In the Linux kernel, the following vulnerability has been resolved: tracing: Do not call map-ops-eltfree if eltalloc fails In paths where tracingmapeltalloc failed to allocate objects, the map-ops-eltalloc call was never successful. In this case, map-ops-eltfree should not be called...

CVE-2026-64028

The Linux kernel contains a vulnerability in the tracing subsystem where the hist_field_name() function can return a NULL value during snprintf() truncation.
