The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from improper calculation of the number of frames in the USB audio driver, potentially leading to...

kernel: ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping

A flaw was found in the Linux kernel’s ASoC Intel bytcrrt5640 driver. When an invalid value is passed via the driver’s “quirk” input option, the driver merely logs an error and retains the invalid value, rather than correcting it. This can result in out-of-bounds OOB memory access...

kernel: Linux kernel ALSA USB audio driver: Buffer overflow leading to information disclosure and denial of service

A flaw was found in the ALSA USB audio driver of the Linux kernel. This vulnerability, a buffer overflow, occurs when the size of the Pulse-Code Modulation PCM stream data packets exceeds the maximum allowed by the USB descriptor. A local attacker could exploit this by providing specially crafted...

CVE-2026-23089

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix use-after-free in sndusbmixerfree When sndusbcreatemixer fails, sndusbmixerfree frees mixer-idelems but the controls already added to the card still reference the freed memory. Later when sndcardregister runs...
