An update for kernel is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerabilit...

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...

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 (Linux kernel: ALSA HDA/Conexant) is about a missing error check in cx_probe() for snd_hda_jack_detect_enable_callback(). The function can return an error pointer on failure (e.g., memory allocation), and the code was ignoring this return value. If registration fails, jack-detectio...

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...

CVE-2026-53052

A flaw was found in the Linux kernel. The Advanced Linux Sound Architecture on Chip ASoC subsystem, specifically within the Qualcomm qdsp6 topology component, fails to verify the type of a virtual widget before accessing its private data. This oversight could allow an attacker to cause incorrect...

CVE-2026-53242

A flaw was found in the Advanced Linux Sound Architecture ALSA Pulse-Code Modulation PCM component of the Linux kernel. This vulnerability involves a corruption of wait queue lists within the sndpcmdrain function when processing linked streams. An attacker could exploit this issue to trigger a...

CVE-2026-53193

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. This vulnerability occurs when a timer object is freed while timer instances are still associated with it, particularly when userspace-driven timers are involved. A local user can exploit this by...

SUSE CVE-2026-53193

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: Forcibly close timer instances at closing When sndtimer object is freed via sndtimerfree and still pending sndtimerinstance objects are assigned to the timer object, it tries to unlink all instances and just set NULL...

CVE-2026-53192

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A race condition can occur during the release of a timer object, specifically when the SNDRVTIMERIOCTLPARAMS ioctl is called concurrently. This can lead to a use-after-free vulnerability, potentially...
