CVE-2026-74601

A flaw was found in the Linux kernel's ring-buffer component. A race condition exists within the ringbufferswapcpu function, where a committing counter can temporarily drop to zero during a write operation. This allows a buffer swap to occur while a write is still in progress, resulting in an...

CVE-2026-74634

A flaw was found in the Linux kernel's ring-buffer component. This vulnerability occurs when the system attempts to change the order of sub-buffers while resizing is disabled, leading to memory being freed prematurely. A local attacker could exploit this use-after-free condition to potentially...

CVE-2026-74602

A flaw was found in the Linux kernel's ring-buffer component. The rballocatecpubuffer function failed to initialize the bpage-order value, leaving it as zero. This uninitialized value is later used by freebufferpage when deallocating ring-buffers with sub-buffers larger than a page size. An...

SUSE CVE-2026-74602

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Initialise reader page order in rballocatecpubuffer In rballocatecpubuffer, bpage-order was omitted, leaving it as 0. This is an issue for a ring-buffer with subbufs bigger than PAGESIZE if when freed: freebufferpage...

CVE-2026-74634

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Prevent subbuf order change when resizing is disabled Because ringbuffersubbuforderset frees buffer pages, we can't allow it when resizing is disabled. A non-consuming reader is at risk of use-after-free rbadvanceite...

CVE-2026-74601

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Use currentcontext for safe per-CPU buffer swap The ringbufferswapcpu function currently checks the per-CPU committing counter to determine if a buffer is actively being written to before performing the swap. However...

CVE-2026-74602

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Initialise reader page order in rballocatecpubuffer In rballocatecpubuffer, bpage-order was omitted, leaving it as 0. This is an issue for a ring-buffer with subbufs bigger than PAGESIZE if when freed: freebufferpage...

CVE-2026-74691 net: thunderbolt: Tear down DMA paths before stopping the rings

In the Linux kernel, the following vulnerability has been resolved: net: thunderbolt: Tear down DMA paths before stopping the rings tbnetteardown stops both rings and frees their frame buffers before calling tbxdomaindisablepaths. tbringstop zeroes the ring's descriptor base and tbnetfreebuffers...

CVE-2026-74691

CVE-2026-74691 is a teardown ordering bug in the Linux kernel Thunderbolt network driver (net: thunderbolt / tbnet). The driver stops its DMA rings and frees frame buffers before deactivating the high-speed DMA paths, but the setup path was previously fixed to enable paths last. Teardown was neve...

CVE-2026-74634

This vulnerability affects the Linux kernel ring-buffer subsystem. The root cause is that ring_buffer_subbuf_order_set() frees buffer pages even when resizing is disabled, leaving a non-consuming reader exposed to a use-after-free in rb_advance_iter(). The fix returns -EBUSY on resize_disabled, m...

CVE-2026-74634 ring-buffer: Prevent subbuf order change when resizing is disabled

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Prevent subbuf order change when resizing is disabled Because ringbuffersubbuforderset frees buffer pages, we can't allow it when resizing is disabled. A non-consuming reader is at risk of use-after-free rbadvanceite...

CVE-2026-74602 ring-buffer: Initialise reader page order in rb_allocate_cpu_buffer()

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Initialise reader page order in rballocatecpubuffer In rballocatecpubuffer, bpage-order was omitted, leaving it as 0. This is an issue for a ring-buffer with subbufs bigger than PAGESIZE if when freed: freebufferpage...

CVE-2026-74601 ring-buffer: Use current_context for safe per-CPU buffer swap

However...

CVE-2026-74602

CVE-2026-74602 is a Linux kernel vulnerability in the ring-buffer subsystem. In rb_allocate_cpu_buffer(), the field bpage->order was left uninitialized (defaulting to 0). This becomes a problem when a ring-buffer uses subbuffers larger than PAGE_SIZE, because free_buffer_page() relies on the c...
