kernel: ALSA: usb-audio: Cancel pending work at closing a MIDI substream

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. This flaw allows a local user to cause a Denial of Service DoS through a system crash. A race condition exists when closing a USB MIDI Musical Instrument Digital Interface output substream because...

kernel: ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and mmap_lock

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix potential AB/BA lock with buffermutex and mmaplock syzbot caught a potential deadlock between the PCM runtime-buffermutex and the mm-mmaplock. It was brought by the recent fix to cover the racy read/write and other...

kernel: ALSA: oss: Fix PCM OSS buffer allocation overflow

In the Linux kernel, the following vulnerability has been resolved: ALSA: oss: Fix PCM OSS buffer allocation overflow We've got syzbot reports hitting INTMAX overflow at vmalloc allocation that is called from sndpcmplugalloc. Although we apply the restrictions to input parameters, it's based only...

kernel: ALSA: pcm: Fix races among concurrent prealloc proc writes

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix races among concurrent prealloc proc writes We have no protection against concurrent PCM buffer preallocation changes via proc files, and it may potentially lead to UAF or some weird problem. This patch applies the...

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.

kernel: Use-after-free in snd_pcm_info function in ALSA subsystem potentially leads to privilege escalation

Use-after-free vulnerability in the sndpcminfo function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it i...

The vulnerability of the Advanced Linux Sound Architecture component in VMware Workstation allows a hacker to execute arbitrary code.

The vulnerability of the Advanced Linux Sound Architecture ALSA component in VMware Workstation hypervisors is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to execute arbitrary code...

The vulnerability in the implementation of the alsa_seq_dummy_init handler in the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the alsaseqdummyinit implementation in the sound/core/seq/snd-seq-dummy.ko module of the Linux operating system is related to a memory leak. Exploiting this vulnerability could allow an attacker to cause a system failure by connecting an ALSA sequencer MIDI-through device. Th...
