CVE-2023-53525 RDMA/cma: Allow UD qp_type to join multicast only

In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Allow UD qptype to join multicast only As for multicast: - The SIDR is the only mode that makes sense; - Besides PSUDP, other port spaces like PSIB is also allowed, as it is UD compatible. In this case qkey also needs t...

CVE-2022-50393

CVE-2022-50393 affects the Linux kernel in the AMDGPU SDMA update path. The root cause is SDMA updating page tables from an unlocked context, triggering a warning in dma_resv_iter_next and related functions (amdgpu_vm_sdma_update, amdgpu_vm_ptes_update, etc.). The issue is mitigated by using an u...

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...
