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...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ring-buffer: Free cpubuffer::freepage with subbuforder When sub-buffers use an order greater than 0, cpubuffer-freepage is allocated with subbuforder. Use the...
CVE-2026-89501
A flaw was found in the Linux kernel's ring-buffer component. A race condition occurs when resizing a sub-buffer without properly holding the cpubuffer::lock. This oversight can lead to concurrency issues with memory allocation and deallocation operations, potentially resulting in system...

CVE-2026-89501
CVE-2026-89501 affects the Linux kernel ring-buffer subsystem. The root cause is a race condition : ring_buffer_subbuf_order_set() can clear cpu_buffer->free_page without holding cpu_buffer::lock, creating a concurrency conflict with ring_buffer_alloc_read_page() and ring_buffer_free_read_page...
CVE-2026-89502
CVE-2026-89502 is a Linux kernel vulnerability in the ring-buffer subsystem. The root cause is that when sub-buffers use a page order greater than 0 , the cpu_buffer->free_page field is allocated using subbuf_order but subsequently freed with the wrong order, leading to an incorrect page relea...
