CVE-2024-53180Public exploit

Kernel panic via uninitialized ALSA DMA mapping

Published Dec 27, 2024 · Updated May 11, 2026

NULL pointer dereference in ALSA PCM mmap handling in affected Linux kernels allows local users to trigger a kernel panic. The default snd_pcm_mmap_data_fault handler calls virt_to_page on runtime->dma_area without first ensuring that the pointer was initialized. Exploitation requires local PCM device access and a driver that permits mmap before initializing its DMA area; the demonstrated consequence is system interruption through a kernel panic.
