CVE-2026-74601: Undefined Security Weakness

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-2026-74634: Undefined Security Weakness

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: Undefined Security Weakness

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-2026-74447

In the Linux kernel (drm/amdkfd), a uint32_t overflow in EOP ring buffer size alignment was fixed. The issue occurred because eop_ring_buffer_size (u32) is aligned with PAGE_SIZE in kfd_queue_acquire_buffers() using 32‑bit arithmetic, allowing a user size like 0xFFFFF001 to wrap to 0 and bypass t...

CVE-2026-68365

The CVE concerns the Linux kernel USB serial driver for io_edgeport. The vulnerability arises because edge_interrupt_callback() adds a 16-bit transmit-credits value to txCredits without enforcing maxTxCredits. edge_write() then uses (txCredits − software FIFO count) as the data that fits, and sin...
