CVE-2025-22049 addresses a vulnerability in the Linux kernel related to the LoongArch architecture. The issue involves the ARCH_DMA_MINALIGN value, which was set to 1 by default but should be increased to 16 to meet the alignment requirements of certain LoongArch-specific devices like APBDMA. Insufficient alignment can cause hardware errors when writing cache lines for small DMA buffers, potentially leading to system instability. The fix increases ARCH_DMA_MINALIGN to 16 to ensure safe memory allocation for DMA operations.
