Description
A flaw was found in the Linux kernel's Advanced Linux Sound Architecture (ALSA) System on Chip (ASoC) Xilinx formatter Pulse-Code Modulation (PCM) driver. During the opening of an audio stream, memory allocated for stream data is not properly released if an error occurs in a subsequent step. This can lead to a memory leak and a dangling pointer, potentially allowing a local attacker to trigger a use-after-free condition, which could result in a system crash or denial of service.
