CVE-2026-89502 ring-buffer: Free cpu_buffer::free_page with subbuf_order
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-2026-89501
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-2026-89501
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...

EUVD-2026-76406
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...
CVE-2026-89500
CVE-2026-89500 is a flaw in the Linux kernel's ring-buffer component. When a cached reader page is discarded after a concurrent ring buffer resize, the kernel uses the new global subbuf_order for the free_pages() call rather than the order under which the page was originally allocated. This misma...

CVE-2026-89498 orangefs: fix double-free of trailer_buf on readdir copy failure
In the Linux kernel, the following vulnerability has been resolved: orangefs: fix double-free of trailerbuf on readdir copy failure On a readdir downcall, orangefsdevreqwriteiter frees op-downcall.trailerbuf with vfree when copyfromiterfull fails, but does not clear the pointer before goto Efault...
CVE-2026-89499
CVE-2026-89499 affects the Linux kernel ring-buffer component. When the remote swap_reader_page callback returns -EBUSY (e.g., during an event storm on a small buffer), __rb_get_reader_page_from_remote() incorrectly continues with an unchanged reader ID and rearranges the local page list as thoug...

CVE-2026-89498
CVE-2026-89498 affects the orangefs (PVFS2) module in the Linux kernel. On a readdir downcall, orangefs_devreq_write_iter() frees op->downcall.trailer_buf via vfree() when copy_from_iter_full() fails but does not clear the pointer before jumping to the error path. The waiter in do_readdir() is...

CVE-2026-89497
A heap buffer overflow exists in the Linux kernel's OrangeFS (orangefs) client, specifically in the function orangefs_prepare_cdm_array(). The function sizes each client debug keyword buffer using strcspn(cds_head, " "), which does not skip leading spaces, but then parses the keyword with the %s ...
