tracing/dma: Cap dma_map_sg tracepoint arrays to prevent buffer overflow

...

The vulnerabilities of the functions test_gen_synth_cmd() and test_empty_synth_event() in the kernel/trace/synth_event_gen_test.c module, which support Linux operating system tracing, allow a malicious actor to cause a service failure.

The vulnerabilities of the functions testgensynthcmd and testemptysynthevent in the kernel/trace/syntheventgentest.c module, which support kernel tracing in Linux operating systems, are related to improper memory release. Exploiting these vulnerabilities could allow an attacker to cause a system...

The vulnerability of the `rb_check_bpage()` function in the kernel/trace/ring_buffer.c module, which supports Linux operating system debugging, allows a malicious actor to cause a service failure.

The vulnerability of the rbcheckbpage function in the kernel/trace/ringbuffer.c module, which is part of the Linux kernel’s tracing support, is related to improper validation of the integrity check value. Exploiting this vulnerability could allow an attacker to trigger a service failure...

The vulnerability of the `register_synth_event()` function in the kernel/trace/trace_events_synth.c module, which supports Linux kernel tracing, allows a malicious actor to access protected information or cause system failures.

The vulnerability of the registersynthevent function in the kernel/trace/traceeventssynth.c module, which supports kernel tracing in Linux operating systems, relates to the execution of operations outside the buffer in memory. Exploiting this vulnerability could allow an attacker to access...

CVE-2026-33249 NATS: Message tracing can be redirected to arbitrary subject

NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Starting in version 2.11.0 and prior to versions 2.11.15 and 2.12.6, a valid client which uses message tracing headers can indicate that the trace messages can be sent to an arbitrary valid subject,...

CVE-2026-33249

NATS-Server vulnerability CVE-2026-33249 affects versions 2.11.0 through 2.11.14 and 2.12.0 through 2.12.5. A valid client using message tracing headers can cause trace messages to be sent to an arbitrary valid subject, including subjects the client cannot publish to; the payload is a valid trace...

CVE-2026-23390

A flaw was found in the Linux kernel. When tracing large scatter-gather lists, which are mechanisms for efficient data transfer, the dmamapsg tracepoint can trigger a performance buffer overflow. This can lead to the tracing buffer becoming too small, potentially causing system warnings and...

SUSE CVE-2026-23309

In the Linux kernel, the following vulnerability has been resolved: tracing: Add NULL pointer check to triggerdatafree If triggerdataalloc fails and returns NULL, eventhisttriggerparse jumps to the outfree error path. While kfree safely handles a NULL pointer, triggerdatafree does not. This cause...

SUSE CVE-2026-23374

In the Linux kernel, the following vulnerability has been resolved: blktrace: fix thiscpuread/write in preemptible context tracingrecordcmdline internally uses thiscpuread and thiscpuwrite on the per-CPU variable tracecmdlinesave, and tracesavecmdline explicitly asserts preemption is disabled via...

SUSE CVE-2026-23380

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose When a process forks, the child process copies the parent's VMAs but the usermapped reference count is not incremented. As a result, when both the parent and child processes exit,...

EUVD-2026-15391

In the Linux kernel, the following vulnerability has been resolved: tracing/dma: Cap dmamapsg tracepoint arrays to prevent buffer overflow The dmamapsg tracepoint can trigger a perf buffer overflow when tracing large scatter-gather lists. With devices like virtio-gpu creating large DRM buffers,...

While kfree safely handles a NULL pointer, triggerdatafree does not. This cause...

CVE-2026-23380

A flaw was found in the Linux kernel. A local user could exploit an issue in the tracing buffer's memory management when a process forks. If an application uses madviseMADVISEDOFORK, it can cause the tracingbuffersmmapclose function to be called multiple times, leading to a system warning and...
