CVE-2026-74653
A flaw was found in the Linux kernel's 8250of serial driver, specifically affecting NXP LPC32xx UARTs. A local user could repeatedly open a specific serial port, triggering a stuck RX character-timeout interrupt. This leads to an interrupt storm that can livelock the CPU, resulting in a Denial of...

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-2026-74356
CVE-2026-74356 concerns the Linux kernel vhost subsystem. The issue is that vhost_get_avail_idx incorrectly reported whether all entries were consumed instead of whether new entries were added to the virtqueue, particularly affecting drivers/vhost/net.c when mergeable buffers are enabled. This mi...
