kernel: ALSA: aloop: Fix peer runtime UAF during format-change stop

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture aloop driver. This Use-After-Free UAF vulnerability occurs when loopbackcheckformat stops the capture side during a format change, while a concurrent close operation detaches or frees the runtime. An attacker could...

CVE-2026-53348

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA System on Chip ASoC SoundWire Digital Audio SDCA component. The sdcadevunregisterfunctions function does not properly check for NULL function device entries during unregistration. This oversight can lead to a NULL point...

UBUNTU-CVE-2026-53350

In the Linux kernel, the following vulnerability has been resolved: ASoC: wmadsp: Fix NULL dereference when removing firmware controls In wmadspcontrolremove check that the priv pointer is not NULL before attempting to cleanup what it points to. When csdsp creates a control it calls...

CVE-2026-53348

In the Linux kernel, the following vulnerability has been resolved: ASoC: SDCA: fix NULL pointer dereference in sdcadevunregisterfunctions sdcadevunregisterfunctions iterates over all SDCA function descriptors and calls sdcadevunregister on each funcdev without checking for NULL. When a function...

Linux Distros Unpatched Vulnerability : CVE-2026-53241

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ALSA: seq: dummy: fix UMP event stack overread The dummy sequencer port forwards events by copying an incoming struct sndseqevent into a stack temporary,...

CVE-2026-45258 Multiple vulnerabilities in the sound(4) mmap path

dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narrowed from 64 to 32 bits when converted to ...

CVE-2026-49417 Multiple vulnerabilities in the sound(4) mmap path

Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-accessible by default. On a system wit...

CVE-2026-49417

CVE-2026-49417 is part of two memory-safety issues in FreeBSD’s sound(4) mmap path. The advisories describe: (1) dsp_mmap_single() could overflow when validating a requested mapping, allowing a mapping to extend past the audio buffer into kernel memory (CVE-2026-45258), and (2) the audio buffer b...

UBUNTU-CVE-2026-53291

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/conexant: Fix missing error check for jack detection In cxprobe, the return value of sndhdajackdetectenablecallback is ignored. This function returns a pointer, and if it fails e.g., due to memory allocation failure, it...

CVE-2026-53291

CVE-2026-53291 affects the Linux kernel ALSA hda/conexant driver. The root cause is the ignored return value from snd_hda_jack_detect_enable_callback() in cx_probe(); if the call fails, an error pointer is returned and not checked, potentially leading to a crash when jack events are handled. The ...

CVE-2026-52963

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA USB audio driver. The driver's handling of MIDI Musical Instrument Digital Interface endpoint descriptors did not properly bound scans, allowing it to read beyond the intended memory buffer. This out-of-bounds read coul...
