CVE-2026-46004: Use After Free

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: Handle probe errors properly The probe procedure of setupcard in caiaq driver doesn't treat the error cases gracefully, e.g. the error from sndcardregister calls sndcardfree but continues. This would lead to a UAF fo...

Linux Distros Unpatched Vulnerability : CVE-2026-46004

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: fixed a reference leak in usbdev on probe failure The createcard function takes a reference to the USB device using usbgetdev, and stores the corresponding usbputdev in cardfree. This function is installed as the...

SUSE CVE-2026-31778

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: fix stack out-of-bounds read in initcard The loop creates a whitespace-stripped copy of the card shortname where len id is used for the bounds check. Since sizeofcard-id is 16 and the local id buffer is also 16 bytes...

SUSE CVE-2026-31701

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: take a reference on the USB device in createcard The caiaq driver stores a pointer to the parent USB device in cdev-chip.dev but never takes a reference on it. The card's privatefree callback, sndusbcaiaqcardfree, ca...

CVE-2026-31778

A flaw was found in the Linux kernel's ALSA caiaq driver. A local user with a specially crafted USB device, containing a product name with many non-ASCII or non-space characters, can trigger a stack out-of-bounds read. This vulnerability allows the system to read past the end of a stack buffer,...

CVE-2026-31778

Summary: CVE-2026-31778 affects the Linux kernel ALSA caiaq driver (init_card) and is caused by an off-by-one in a whitespace-stripping loop that copies a card id. The 16-byte local buffer can be filled without leaving space for the terminating null, causing a non-null-terminated string to be pas...
