Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition in the ALSA PCM OSS layer can lead to a use-after-free (UAF) issue. This occurs when the layer attempts to clear the buffer with silence data during stream initialization or reconfiguration, using the
snd pcm format set silence() function with runtime->dma area. The accessed runtime->dma area might be freed concurrently, as this operation is performed outside the PCM ops. To avoid this, the code has been moved into the PCM core and is now performed inside the buffer access lock.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
