Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Limits the period size to 16MB. We have set a practical limit on the period size the fragment shift in OSS, instead of using a full 31-bit value. A too-large value could lead to memory exhaustion, as we allocate...
