CVE-2026-56109

The CVE concerns ALSA Library prior to 1.2.16.1, where a double-free occurs in parse_def() (src/conf.c) due to not validating return values when parsing nested compound or array configuration blocks. This can cause snd_config_delete() to be invoked twice on an already-freed node, leading to NULL-...

kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. An inconsistency in how USB audio playback and capture streams are handled can lead to an out-of-bounds write to a memory buffer. This can result in a system crash, causing a denial of service for a...

CVE-2026-46048

CVE-2026-46048 relates to a leak in the Linux kernel ALSA caiaq driver. The issue arises because create_card() takes a usb_get_dev() reference to a USB device and stores the corresponding usb_put_dev() in card_free(), which is registered as snd_card’s private_free destructor. However, private_fre...
