CVE-2022-50375

In the Linux kernel, the following vulnerability has been resolved: tty: serial: fsllpuart: disable dma rx/tx use flags in lpuartdmashutdown lpuartdmashutdown tears down lpuart dma, but lpuartflushbuffer can still occur which in turn tries to access dma apis if lpuartdmatxuse flag is true. At thi...

CVE-2023-53393 RDMA/mlx5: Fix mlx5_ib_get_hw_stats when used for device

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix mlx5ibgethwstats when used for device Currently, when mlx5ibgethwstats is used for device portnum = 0, there is a special handling in order to use the correct counters, but, portnum is being passed down the stack...

CVE-2022-50393

The CVE-2022-50393 issue affects the Linux kernel DRM/AMDGPU SDMA path where dma_resv_iter_next may be invoked from an unlocked context during SDMA page-table updates, leading to a potential misuse warning and race conditions. Affected component: amdgpu driver within the kernel's DMA-BUF handling...

CVE-2022-50375 tty: serial: fsl_lpuart: disable dma rx/tx use flags in lpuart_dma_shutdown

In the Linux kernel, the following vulnerability has been resolved: tty: serial: fsllpuart: disable dma rx/tx use flags in lpuartdmashutdown lpuartdmashutdown tears down lpuart dma, but lpuartflushbuffer can still occur which in turn tries to access dma apis if lpuartdmatxuse flag is true.

CVE-2022-50375

CVE-2022-50375 affects the Linux kernel: the fix ensures that in lpuart_dma_shutdown the flags for lpuart_dma_tx_use and lpuart_dma_rx_use are set to false. Without this, lpuart_flush_buffer could access DMA APIs after DMA teardown, causing aborts. The patch prevents DMA access after relinquishme...
