CVE-2026-43061

CVE-2026-43061 (Linux kernel): The serial8250 TX DMA deadlock was fixed. The root cause was that dmaengine_terminate_async did not guarantee the __dma_tx_complete callback would run, and that callback is the only place where dma->tx_running is cleared. If a TX DMA transaction is canceled and t...

CVE-2026-43031

A flaw was found in the Linux kernel's xilinx axienet network driver. This vulnerability arises from incorrect accounting of Buffer Queue Length BQL, a mechanism that manages network buffer usage, for transmit TX packets that are split across multiple buffer descriptors. If these packet segments...

CVE-2026-31700

In the Linux kernel, the following vulnerability has been resolved: net/packet: fix TOCTOU race on mmap'd vnethdr in tpacketsnd In tpacketsnd, when PACKETVNETHDR is enabled, vnethdr points directly into the mmap'd TX ring buffer shared with userspace. The kernel validates the header via...

CVE-2026-43031 net: xilinx: axienet: Fix BQL accounting for multi-BD TX packets

In the Linux kernel, the following vulnerability has been resolved: net: xilinx: axienet: Fix BQL accounting for multi-BD TX packets When a TX packet spans multiple buffer descriptors scatter-gather, axienetfreetxchain sums the per-BD actual length from descriptor status into a caller-provided...

CVE-2026-43031

The CVE concerns the Linux kernel xilinx axienet driver. When a TX packet spans multiple buffer descriptors, the current accounting in axienet_free_tx_chain summing per-BD lengths into an accumulator can lose earlier bytes if the packet completes across different polls, causing BQL to overestimat...
