CVE-2021-47511 ALSA: pcm: oss: Fix negative period/buffer sizes
In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Fix negative period/buffer sizes The period size calculation in OSS layer may receive a negative value as an error, but the code there assumes only the positive values and handle them with sizet. Due to that, a to...
CVE-2021-47509
In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Limit the period size to 16MB Set the practical limit to the period size the fragment shift in OSS instead of a full 31bit; a too large value could lead to the exhaust of memory as we allocate temporary buffers of...
