Link DMA Release Issue in Intel ASoC Driver for Linux Kernel

CVE-2024-57805

Summary

A vulnerability in the ASoC: SOF: Intel driver for the Linux kernel could allow a temporary mismanagement of link DMA resources. When a stream is stopped, the link DMA should remain allocated to prevent other streams from seizing it during a critical window. Failure to maintain this allocation can lead to unpredictable behavior, including firmware errors or system crashes, especially if another stream is initiated in quick succession. This issue may not occur under normal usage patterns but can be exploited under specific conditions.
