kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

CVE-2026-10644

The Microchip SERCOM-G1 UART driver drivers/serial/uartmchpsercomg1.c, used by the PIC32CM-JH SoC family, contains an out-of-bounds write in its asynchronous DMA receive path. When uartrxenable is invoked with a one-byte receive buffer len == 1 and CONFIGUARTMCHPASYNC is enabled, the RX-complete...
