Linux Distros Unpatched Vulnerability : CVE-2026-89747

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tracing: Fix use-after-free in tracepipe read on sub-buffer order change Writing to buffersubbufsizekb calls ringbuffersubbuforderset, which frees every...

EUVD-2026-76659

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix use-after-free in tracepipe read on sub-buffer order change Writing to buffersubbufsizekb calls ringbuffersubbuforderset, which frees every sub-buffer of the ring buffer, including the reader page, and replaces them...

CVE-2026-89747

CVE-2026-89747 is a use-after-free vulnerability in the Linux kernel tracing subsystem , specifically in the trace_pipe read path. Writing to buffer_subbuf_size_kb triggers ring_buffer_subbuf_order_set(), which frees all sub-buffers (including the reader page) while active trace_pipe readers stil...

CVE-2026-89747: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix use-after-free in tracepipe read on sub-buffer order change Writing to buffersubbufsizekb calls ringbuffersubbuforderset, which frees every sub-buffer of the ring buffer, including the reader page, and replaces them...

CVE-2026-89771: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Fix subbuf resize race with ring buffer readers tracebuffer subbufsize is read lockless in ringbufferreadpage and ringbufferreadstart, while it can simultaneously be resized with ringbuffersubbuforderset. Instead of...

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

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

CVE-2023-53709: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Handle race between rbmovetail and rbcheckpages It seems a data race between ringbuffer writing and integrity check. That is, RBFLAG of headpage is been updating, while at same time RBFLAG was cleared when doing...

CVE-2023-53718: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Do not swap cpubuffer during resize process When ringbufferswapcpu was called during resize process, the cpu buffer was swapped in the middle, resulting in incorrect state. Continuing to run in the wrong state will...

The vulnerability in the kernel/trace/ring_buffer.c component of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability in the kernel/trace/ringbuffer.c component of the Linux operating system is related to the use of memory after it has been freed. Exploiting this vulnerability can allow an attacker to cause a service failure...
