CVE-2024-53180

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

ALSA: pcm: Add sanity NULL check for the default mmap fault handler

A driver might allow the mmap access before initializing its runtime->dma_area properly. Add a proper NULL check before passing to virt_to_page() for avoiding a panic.
