CVE-2021-47096

In the Linux kernel, the following vulnerability has been resolved: ALSA: rawmidi - fix the uninitalized userpversion The userpversion was uninitialized for the user space file structure in the open function, because the file private structure use kmalloc for the allocation. The kernel ALSA...

ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF

A use-after-free flaw was found in sndctlelemread in sound/core/control.c in Advanced Linux Sound Architecture ALSA subsystem in the Linux kernel. In this flaw a normal privileged, local attacker may impact the system due to a locking issue in the compat path, leading to a kernel information leak...
