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...

EUVD-2026-76409

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ringbufferallocreadpage is racy with ringbuffersubbuforderset, it can allocate a reader page with an outdated order.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...

EUVD-2026-76408

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...

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...

CVE-2026-89500

CVE-2026-89500 affects the Linux kernel ring-buffer subsystem. The flaw resides in cpu_buffer::free_page: when a cached reader page is discarded after a concurrent ring buffer resize , the free_pages() call uses the new global subbuf_order rather than the order under which the page was originally...
