CVE-2026-80829

A flaw was found in the Linux kernel's ALSA USB audio driver. A local attacker with a specially crafted USB device could exploit this vulnerability. By providing a malformed wMaxPacketSize value, the device can trigger an out-of-bounds write in the kernel's memory. This memory corruption could le...

CVE-2026-98837

A flaw was found in the Linux kernel's ALSA caiaq USB audio driver. This flaw allows a local attacker to cause a Denial of Service DoS or potentially escalate privileges. When device initialization fails during the probing process, the driver frees internal device state structures while leaving t...

CVE-2026-98836

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture Line 6 USB audio driver. The driver fails to validate the size of playback packets against the allocated memory buffer slice when handling asymmetrical audio configurations. An attacker capable of connecting a crafted U...

CVE-2026-90033

A flaw was found in the Linux kernel's ALSA USB audio subsystem. The sndusbmidius122loutput function, responsible for handling USB MIDI output, incorrectly calculates the buffer size for devices operating at slower than high speed. This error can lead to an out-of-bounds write, where the system...

CVE-2026-98769

A flaw was found in the Linux kernel's Universal Serial Bus USB audio gadget driver. A connected USB host can send a specially crafted audio control request with an invalid command index, causing an out-of-bounds heap memory read and write. This flaw primarily allows an attacker to cause a Denial...

CVE-2026-98741

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture UA-101 USB audio driver. The driver does not validate that packet sizes and channel numbers match between capture and playback endpoints during device initialization. An attacker who connects a specially crafted USB...
