EUVD-2022-54958

26.02.2025, 07:01

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

ASoC: SOF: Intel: Fix NULL ptr dereference when ENOMEM

Do not call snd_dma_free_pages() when snd_dma_alloc_pages() returns
-ENOMEM because it leads to a NULL pointer dereference bug.

The dmesg says:
