CVE-2026-63929

The CVE-2026-63929 issue is in the Linux kernel iio subsystem, specifically iio_buffer_enqueue_dmabuf() which allocates a iio_dma_fence and calls dma_resv_add_fence(). The initial reference from dma_fence_init() (kref=1) is not released on the success path, while dma_resv_add_fence() takes a seco...

CVE-2026-63910

In the Linux kernel, the following vulnerability has been resolved: dma-buf: fix UAF in dmabuffd tracepoint Once FDADD returns, the fd is live in the file descriptor table and a thread sharing that table can close it before DMABUFTRACE runs. The close drops the last reference, fput frees the...

CVE-2026-63910

The CVE-2026-63910 entry describes a Linux kernel vulnerability in dma-buf: a slab-use-after-free (UAF) in the dma_buf_fd() tracepoint. The fault arises because FD_ADD() leaves the allocated file descriptor live in the table; a racing thread can close() the fd before the DMA_BUF_TRACE() tracepoin...

CVE-2026-63883 serial: qcom_geni: fix kfifo underflow when flush precedes DMA completion IRQ

In the Linux kernel, the following vulnerability has been resolved: serial: qcomgeni: fix kfifo underflow when flush precedes DMA completion IRQ When uartflushbuffer runs before the DMA completion IRQ is delivered, the following race can occur all steps serialized by uartportlock: 1. DMA starts:...

CVE-2026-63883

The CVE relates to the Linux kernel serial driver for Qualcomm GENI: a kfifo underflow race when uart_flush_buffer() runs before the DMA completion IRQ. The race sequence can cause stale DMA data to be submitted due to kfifo_len() being reset to 0 while tx_remaining is nonzero, leading to an inco...
