Astra Linux – Vulnerability in Linux, Linux 5.10

It was discovered that there was a lack of CPU resources in the Linux kernel tracing module functionality in versions prior to 5.14-rc3. This issue occurred due to the way users utilize the trace ring buffer. Only privileged local users with the CAPSYSADMIN capability could exploit this flaw to...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: Ring-buffer: Do not attempt to read beyond the “commit” boundary. When iterating over the ring buffer while the ring buffer is active, the writer can corrupt the reader’s data. There are mechanisms to detect and handle this issue...

SUSE CVE-2026-89499

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Stop remote reader update when page swap fails The remote swapreaderpage callback can return -EBUSY when the writer moves the head before the remote catches it, particularly during an event storm on a small buffer...

SUSE CVE-2026-89500

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Make cpubuffer::freepage a bufferdatareadpage Discarding a cached reader page after a concurrent ring buffer resize uses the new global subbuforder for the freepages call. This mismatched order may crashes the kernel...

SUSE CVE-2026-89501

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Hold cpubuffer::lock when resizing a subbuf Because, ringbuffersubbuforderset can clear cpubuffer-freepage, hold cpubuffer-lock to prevent races with ringbufferallocreadpage and ringbufferfreereadpage...

SUSE CVE-2026-89502

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Free cpubuffer::freepage with subbuforder When sub-buffers use an order greater than 0, cpubuffer-freepage is allocated with subbuforder. Use the correct order for cpubuffer-freepage...

SUSE CVE-2026-89503

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Fix subbuf resize race with ringbufferallocreadpage ringbufferallocreadpage is racy with ringbuffersubbuforderset, it can allocate a reader page with an outdated order. This isn't a big issue, the user can still...

SUSE CVE-2026-89748

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix retry exhaustion in simple ring buffer reader swap simpleringbufferswapreaderpage starts with retry set to 8 and post-decrements it only after a failed link replacement. On the final attempt, a successful replacement...

SUSE CVE-2026-89771

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...

CVE-2026-89500

A flaw was found in the Linux kernel's ring-buffer component. When a cached reader page is discarded after a concurrent ring buffer resize, the system may use an incorrect buffer size for memory deallocation. This mismatch can lead to a kernel crash, resulting in a Denial of Service DoS, or it...
