CVE-2026-74653

CVE-2026-74653 affects the Linux kernel 8250_of serial driver on NXP LPC32xx (PORT_LPC3220) hardware. The UART can latch an RX character-timeout interrupt while the RX FIFO is empty; because the interrupt is level-triggered and re-fires immediately, it causes an interrupt storm that livelocks the...

CVE-2026-74626

CVE-2026-74626 affects the Linux kernel's Non-Transparent Bridge (NTB) virtual ethernet driver (ntb_netdev). The root cause is in ntb_netdev_rx_handler(), which hands the received skb to the network stack before allocating its replacement. When the allocation fails, the buffer is not reposted, so...

CVE-2026-74622

CVE-2026-74622 is a resource leak in the Linux kernel's Aquantia (AQC) atlantic network driver. The function aq_ring_rx_deinit() only iterates over the [sw_head, sw_tail) region of the RX ring, but since the page reuse strategy was introduced, consumed-but-not-yet-refilled buffers reside in the c...

CVE-2026-74613

CVE-2026-74613 is a use-after-free in the Linux kernel's vsock/virtio transport (net/vmw_vsock/virtio_transport.c). A prior commit (b917507e5ad9) made the RX worker jump to a common exit path when rx_run is clear, but that path still refills the RX queue when the buffer count is low. Work queued ...
