CVE-2026-74691

CVE-2026-74691 is a bug in the Linux kernel's thunderbolt networking driver (net: thunderbolt). The tbnet_tear_down() function stops DMA rings and frees frame buffers before deactivating DMA paths, meaning in-flight DMA has no valid destination to drain to. The teardown order was never updated to...

CVE-2026-74655

This vulnerability affects the qcom-geni serial driver in the Linux kernel . When a transmit flush is issued during an ongoing TX DMA transfer, the UART gets stuck infinitely repeating corrupted TX DMA frames , and a subsequent tcdrain call hangs forever . The root cause is a missing flush_buffer...

CVE-2026-74654

This Linux kernel vulnerability affects the serial 8250 DMA driver . When a serial port is closed while an RX DMA transfer is active, serial8250_release_dma() leaves the rx_running flag set. On subsequent reopen, the DesignWare BUSY workaround calls serial8250_rx_dma_flush() before a new RX chann...

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...
