CVE-2026-80816

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA FireWire Control Protocol FCP driver. Incorrect handling of the Universal Serial Bus Request Block URB for the notification endpoint could lead to a system crash. This occurs because the fcpinitnotify function uses a...

SUSE CVE-2026-98837

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: unregister the input device when probe fails setupcard registers the input device, whose name and phys point into struct sndusbcaiaqdev, and then goes on to sndcardregister and sndusbcaiaqcontrolinit. If either fails...

CVE-2026-98086

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA subsystem. When configuring Universal MIDI Packet UMP devices, the driver prematurely treats endpoint structures as fully initialized before legacy MIDI data structures are attached. A local user or connected device...

CVE-2026-98742

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer subsystem. A local user could exploit a race condition caused by missing locking during compatibility ioctl input/output control operations. By sending concurrent port creation requests, an attacker can corrup...

ALSA-2026:87375 Important: kernel security update

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: ipv4: raw: reject IPHDRINCL packets with ihl msiperm after freeing it on init failure CVE-2026-89777 For more details about the security issues, including the impact, a CVSS score,...

ALSA-2026:87374 Important: kernel-rt security update

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fixes: kernel: ipv4: raw: reject IPHDRINCL packets with ihl msiperm after freeing it on init failure CVE-2026-89777 For more details about the...

CVE-2026-80828

A flaw was found in the ALSA Advanced Linux Sound Architecture USB audio driver in the Linux kernel. When a system resume operation fails for a USB audio device, the driver's error handling is incomplete. This can leave the audio card in an unusable state, blocking further control access and...

CVE-2026-80815

A flaw was found in the ALSA scarlett2 driver in the Linux kernel. This issue arises from the driver's improper management of Universal Serial Bus Request Blocks URBs for notification endpoints, where an already allocated URB is reused without proper re-initialization. This can lead to a system...

CVE-2026-89979

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA Pulse Code Modulation PCM subsystem. A race condition exists where a thread can initiate a PCM start operation while another thread is performing non-atomic PCM operations, such as hardware parameter setup or preparatio...

CVE-2026-93184

A flaw was found in the Advanced Linux Sound Architecture ALSA System on Chip ASoC Freescale Audio Mixer fslaudmix driver in the Linux kernel. During the driver's initialization probe phase, the audio mixer hardware is powered off after runtime power management is enabled. Subsequent attempts to...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2025-38105)

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Kill timer properly at removal The USB-audio MIDI code initializes the timer, but in a rare case, the driver might be freed without the disconnect call. This leaves the timer in an active state while the assigned...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-46018)

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: stop parsing UAC2 rates at MAXNRRATES parseuac2sampleraterange caps the number of enumerated rates at MAXNRRATES, but it only breaks out of the current rate loop. A malformed UAC2 RANGE response with additional...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-46146)

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Avoid potential endless loop in convertchmapv3 The convertchmapv3 has a loop with its increment size of csdesc-wLength, but we forgot to validate csdesc-wLength itself, which may lead to potential endless loop by...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2024-56657)

In the Linux kernel, the following vulnerability has been resolved: ALSA: control: Avoid WARN for symlink errors Using WARN for showing the error of symlink creations don't give more information than telling that something goes wrong, since the usual code path is a lregister callback from each...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-53242)

In the Linux kernel, the following vulnerability has been resolved: ALSA: PCM: Fix wait queue list corruption in sndpcmdrain on linked streams sndpcmdrain uses initwaitqueueentry which does not clear entry.prev/next, and addwaitqueue with a conditional removewaitqueue that is skipped when tocheck...
