CVE-2024-44949 addresses a vulnerability in the Linux kernel's parisc architecture related to DMA corruption. The issue arises because the ARCH_DMA_MINALIGN value was set too low (16 bytes), potentially allowing two unrelated 16-byte allocations to share a cache line. If one allocation is written via DMA and the other via cached write, the DMA-written value may become corrupted. The fix involves increasing ARCH_DMA_MINALIGN to match the largest cache line size for different parisc microarchitectures, preventing such corruption.
