kernel: ALSA: ymfpci: Create card with device-managed snd_devm_card_new()

A flaw was found in the Linux kernel's ALSA ymfpci sound driver. During a previous refactoring commit that removed sndcardymfpciremove, the sndcardnew call was not updated to snddevmcardnew. This omission means sndcardfree is never called during module unload, leading to a kernel oops when...

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.

SUSE CVE-2007-4571

The sndmemprocread function in sound/core/memalloc.c in the Advanced Linux Sound Architecture ALSA in the Linux kernel before 2.6.22.8 does not return the correct write size, which allows local users to obtain sensitive information kernel memory contents via a small count argument, as demonstrate...

The vulnerability of the ALSA:pcm component (the audio subsystem of the Linux operating system), which allows a hacker to cause a service failure and gain unauthorized access to protected information.

The vulnerability of the ALSA:pcm component the audio subsystem of the Linux operating system is related to a synchronization violation in sndctlelemreaduser. Exploiting this vulnerability can allow an attacker to cause service failures and gain unauthorized access to protected information...

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

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Cancel pending work at closing a MIDI substream At closing a USB MIDI output substream, there might be still a pending work, which would eventually access the rawmidi runtime object that is being released. For...

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 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...

Denial Of Service (DoS)

The kernel packages contain the Linux kernel, the core of any Linux operating system. A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol SCTP implementation handled simultaneous connections between the same hosts. A remote attacker could u...

USN-3798-1: Linux kernel vulnerabilities

Dmitry Vyukov discovered that the key management subsystem in the Linux kernel did not properly restrict adding a key that already exists but is negatively instantiated. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2015-8539 It...
